During the 2008 election, CTV and its pollster the Strategic Counsel attempted a different look at the state of the race. With an idea undoubtedly inspired by the close red-blue states in recent American elections, they attempted to pick the closest races in three Canadian provinces and argued that the outcome of these races would determine the outcome of the election.
Points for trying something new, but as I've argued here
previously, more of the ridings that changed hands in the 2000, 2004 and 2006 general elections had previously been won by more than 5% than had been won by less than 5%. Simply being a close-margin riding last time is no guarantee of being a close-margin riding this time, nor one that changes hands party-wise. Other factors, such as incumbency, which party is the government, the strength of the local candidates, and other local and regional factors, play at least as big a role as previous margins of victory.
In fact once we examine the current set of results, we see that this pattern repeated itself again in the 2008 General Election:
- Of the 42 Ridings that changed hands party-wise in 2008, 19 had been won by <= 5% in 2006, while 23 were won by > 5%.
- In other words just 19 of the 49 "Closest Contests" in 2006 (i.e., ridings won by <= 5% in 2006) subsequently changed hands in 2008, while the other 30 of them did not.
- Moreover, only 13 of the 42 "Closest Contests" in 2008 were also among the 49 "Closest Contests" in 2006 .
- So, only 13 ridings in Canada were settled by 5% or less in both 2006 and 2008. Just under half of them, 6 in fact, actually changed hands in 2008 (West Nova, NS; Saint John, NB; Papineau, QC; Welland, ON; London West, ON; and Vancouver Island North, BC). And only 2 of those (Papineau, QC and Vancouver Island North, BC) had changed hands in 2006 as well.
OK, so "close ridings" are not necessarily "swing ridings", nor necessarily close the next time around. But another claim that CTV and the Strategic Counsel made was that these ridings would decide the 2008 election. Does that assertion hold up?
Well, the change in winners of the "Battleground Ridings" did predict the direction of the election's outcome, but only about one-third of the magnitude of the swing from the Liberals to the Conservatives (and to a lesser extent the NDP).

Seven of the Ontario "battleground" ridings changed hands since 2006 (all previously held by the Liberals; 4 went to the Conservatives and 3 to the NDP). Two of the Quebec "battleground" ridings changed hands (the Bloc picked up a Conservative seat, and the Liberals picked up a Bloc seat). And four of the B.C. "battleground" ridings changed hands (the Conservatives picked up 1 NDP and 3 Liberal seats).
In other words, of the 42 ridings that changed hands party-wise in 2008 as compared with their 2006 General Election results, only 13 were found amongst the 45 CTV-Strategic Counsel battleground ridings (
CTV counts 14, but they include changes since dissolution such as
Halton, ON, where incumbent Garth Turner was elected as a Conservative but crossed the floor and ran for re-election as a Liberal). Another 14 were from provinces other than Ontario, Quebec and British Columbia. And the remaining 15 were Ontario, Quebec and BC ridings not included in the CTV-Strategic Counsel "battleground riding" list.
I do think it's interesting to try and predict ahead of time the battlegrounds on which an election will be fought. Unfortunately, I think the "close margin battleground" approach might be better suited for countries with two-party systems, whose elections turn on the votes of a few swing states. With Canada's multi-party parliamentary system, its 308 ridings spread across very distinct regions, each having different sets of parties in contention, this approach was perhaps not ideal.
If I were picking ridings to watch, I would have selected all the
3-way and
4-way races from last time, the seats with
retiring incumbents,
floor-crossers, or where
previous incumbents were coming back to challenge the first-time incumbents who had defeated them in 2006, along with the traditional
bellwether seats such as
Peterborough, ON and
Ottawa West – Nepean, ON. In this election I would also have added in
the likely target ridings of the Conservative Party's ethnic outreach campaign, along with Quebec ridings where the Conservatives placed second in 2006 that had
a military presence, and
rural Maritime ridings especially those with no incumbent.
For the record, here are the CTV-Strategic Counsel Battleground Ridings for the 2008 General Election, their 2006 (or last by-election) margins of victory and contests, and their 2008 margins of victory and contests.
