Canada: "The Progressives", a Fiction

A green maple leaf, recoloured from Image:Cons...Image via Wikipedia
So I'm looking at the newest EKOS numbers - they have a few extra parameters this week. I've been considering a particular fiction that crops up every now and then: the idea that more unity existed on the left side of the spectrum. I'm not talking about some grand coalition or merger between the Liberals and the NDP; considering the Liberals to be what Trudeau once called the 'radical middle', I consider the three mainstream parties that have left-of-centre platforms (regardless of the political alliegances of their supporters): the NDP, the Bloc Québécois and the Green Party.



Let's consider a particular fiction: that these three parties somehow merged and shed no support to other parties. Would it affect the political landscape? Wow, would it ever:

  • Nationwide, the Progressives have a slight lead over the Conservatives at 35.5% to 34.4%. The Liberals trail at 27.8%.
  • In BC, the Conservatives have a slight lead, at 40.9% to the Progressives' 38.7%. The Liberals are far behind at 16.3% (though British Columbians are to pollsters as Samoans are to anthropologists).
  • 'Fortress Alberta' remains firmly in Conservative hands with an amazing 61.8%. The Progressives and the Liberals are far behind at 19.9% and 15.0%.
  • The Prairies are also safe for the Conservatives, with 45.0%. The Progressives are in second at 30.7%, with the Liberals trailing at 20.2%.
  • Ontario is a tight race between the Conservatives at 37.8% and the Liberals at 37.3%. The Progressives trail at 23.8%.
  • 'Fortress Québec' remains firmly in Progressive hands, with a remarkable 59.8%. The Liberals and the Conservatives trail at 24.0% and 13.7% respectively.
  • Atlantic Canada has the Liberals out front at 37.0%, but it's a rather tight race, with the Progressives polling second at 33.7% and the Conservatives at third at 26.9%.
  • Urban centres look like the following:
    • Vancouver: CPC 43.6%, Prog 34.0%, Libs 16.5%
    • Calgary: CPC 57.6%, Libs 22.0%, Prog 16.0%
    • Toronto: Libs 44.4%, CPC 35.8%, Prog 17.9%
    • Ottawa: Libs 37.5%, CPC 35.0%, Prog 27.5%
    • Montréal: Prog 62.6%, Libs 27.2%, CPC 8.1%
  • The gender gap is strong.
    • Nationwide, the Conservatives lead among men at 40.0% to the Progressives' 32.4% and the Liberals' 25.8%.
    • Women, on the other hand, put the Progressives ahead at 38.6% with the Liberals in second at 29.9% and the Conservatives in third at 28.5%
  • Huge gaps surround age too.
    • Under 25s have the Progressives at 45.1 to the Liberals' and Conservatives' 26.5% and 25.4%.
    • The 25-44 age group also has the Progressives in the lead at 38.6%, but the Conservatives overtake the Liberals 31.8% to 27.1%.
    • In the 45-64 group, the Conservatives overtake the Progressives 36.3% to 34.8%. The Liberals trail at 26.7%.
    • In the 65+ group, the Conservatives are well in the lead at 41.8%. The Liberals pass the Progressives 32.4% to 24.1%.
  • Country of birth matters as well.
    • Canadian-born Canadians have the Progressives ahead at 38.0%, with the Conservatives at 32.8% and the Liberals in the basement at 26.2%.
    • Foreign-born Canadians put the Liberals in the lead, however, with 38.1% to the Conservatives' 31.4%. The Progressives trail at 27.8%.
  • Education also makes a significant difference.
    • People with no post-secondary education put the Conservatives and the Progressives almost exactly equal, at 38.3% and 38.0% respectively. The Liberals trail at 20.7%.
    • People with a college or CEGEP education are similar, though they push the Progressives ahead at 36.4% to the Conservatives' 34.5%. The Liberals again trail at 25.7%.
    • Among university grads, though, the split is effectively three-way, with the Liberals at a slight lead with 33.8% over 33.2% for the Progressives. The Conservatives keep it tight at 31.9%

Quite interesting, no? Considering it this way shows a rough three-way split nationwide but all kids of variation across demographics. Looking at these stats a little more graphically, in each case I'm forgetting the numbers and just looking at the one-two-three positions, colouring them blue for Conservatives,  red for Liberals and green for the theoretical Progressives:
  • #1, #2, #3: Nationwide
  • #1, #2, #3: BC
  • #1, #2, #3: Alberta
  • #1, #2, #3: Prairies
  • #1, #2, #3: Ontario
  • #1, #2, #3: Québec
  • #1, #2, #3: Atlantic
  • #1, #2, #3: Vancouver
  • #1, #2, #3: Calgary
  • #1, #2, #3: Toronto
  • #1, #2, #3: Ottawa
  • #1, #2, #3: Montréal
  • #1, #2, #3: Men
  • #1, #2, #3: Women
  • #1, #2, #3: Under 25
  • #1, #2, #3: 25-44 years old
  • #1, #2, #3: 45-64 years old
  • #1, #2, #3: 65+
  • #1, #2, #3: Canadian-born
  • #1, #2, #3: Foreign-born
  • #1, #2, #3: High school
  • #1, #2, #3: College / CEGEP
  • #1, #2, #3: University grads
Or, what is probably a better way to view this whole mess:

  • #1, #2, #3: Nationwide, 25-44 years old, Canadian-born, College / CEGEP
  • #1, #2, #3: BC, Alberta, Prairies, Vancouver, Men, 45-64 years old, High school
  • #1, #2, #3: Ontario, Calgary, Toronto, Ottawa, 65+, Foreign-born
  • #1, #2, #3: Québec, Montréal, Women, Under 25
  • #1, #2, #3: Atlantic, University grad
There is no demographic ranking Liberals first, Conservatives second and Progressives third.

Canada: Polling houses and provinces

So this week, Ipsos Reid, Environics and Ekos have all released polls. They don't have the same sample sizes and they don't cover exactly the same dates. The three houses have slightly different methodologies and tend to produce differing results. Yet despite all of this, they have pretty close numbers at the moment nationwide. For example, Ipsos Reid puts the Conservatives at 34% nationwide, Environics has them at 35% and Ekos, which typically gives the lowest Tory numbers, has them at 32.4%. All well within the margin of error. Ipsos Reid and Environics have the exact same numbers for the Liberals, Ekos has them lower by little more than 2%. All in all, pretty good numbers. So good, in fact, that we can conclude that (a) the three houses must be doing reasonably good jobs if their numbers are so similar, and (b) these numbers must be pretty accurate, if three different polling houses have produced them, more or less.

National Voting Intentions, September 2010

The national sample size is going, of course, to be some ten times larger than the sample size of each province. Of course as a result the margin of error is going to be greater at the provincial level. But what strikes you looking at the three houses is just how deviant their provincial numbers are from each other, in spite of their similarities at the national level. It's an interesting paradox that unreliable numbers at the provincial level can combine to produce more reliable numbers at the national level, but it's a fact of statistics that deviation gets 'rounded out' as numbers increase. Still, it's tough to make any real statements at all about what's going on provincially based on these three polls.

For example, let's look at the four-province megaregion pollsters call 'the Atlantic'. The four provinces east of Québec all obviously have different voting trends and traditions, but due to their relatively smaller population bases are still lumped together in polls. Look at each of the three pollsters, though, and you get a remarkably different picture of these provinces.

Atlantic Voting Intentions, September 2010

Ipsos Reid has the Liberals at 48%, domination on a level we rarely see anymore. Ipsos Reid will tell you that just slightly less than half of all Atlantic Canadians are planning to vote Liberal. Ekos, on the other hand, has the Liberals slightly behind the Conservatives - 32.5% to 33.2%, with the NDP doing historically well at 22.4% in a legitimately tripartisan race: numbers that might be plausible in Nova Scotia, but as for the other three provinces? Environics, on the other hand, not only agrees with Ekos by putting the Conservatives first but puts them far ahead, at 35% to the Liberals' 31%. Has Danny Williams's ABC campaign lost its fizzle? Or are these numbers just all over the place?

BC Voting Intentions, September 2010

Going from one coast to the other, we have BC. Now, yes, BC is notoriously volatile. And yes, BC is legitimately three-way (or even four-way) to an extent unheard-of in any other anglophone province. But... Ekos puts the NDP ahead at 30.8% and has the Conservatives and the Liberals neck-and-neck at 27.0% and 26.5% respectively (and Green at 15.0%). Those numbers might be plausible if surprising, but contrast them with the other two: Ipsos has the NDP at a sad third with 21% behind a surging CPC at 41% and the Liberals at 25% (Green at 13%). Environics also has the NDP at third at 23%, well behind the Liberals at 30% and the Conservatives at 35% (Green at 10%). Admire that range: are the NDP polling 31% or 21%? Are the Tories polling a sad 27% or a mighty 41%?

The national numbers produced by these polling houses provide great talking points. But come election day national numbers mean nothing (remember 1993, where 16% of the national vote got the PCs two seats but 14% of the vote got the BQ 54 seats). And just how much can we trust these polling companies to give us useful provincial (in fact regional) data when it's so very hit-and-miss?
