A couple of months ago the Conservatives chose Andrew Scheer as their new leader. They did so using an electoral system that gave equal weight to Conservative members across all ridings. In the leadership race, candidates received points based on the percentage of vote that they won in each riding. Candidates were eliminated until one, Scheer, had won at least 50% of the available points. This system is designed to ensure that the leader the party chooses has support across the country, not just in Conservative strong-holds. An examination of where Scheer won votes shows that he did better in ridings that were more Conservative than in ridings that were less Conservative. At the same time, he was still more popular than his closes rival, Maxime Bernier, in the ridings that were swing ridings for the Conservatives in the last two elections.
The two graphs below show the percentage of the vote that Andrew Scheer won in each riding on the final ballot count (which included just Scheer and Bernier) compared to the margin of Conservative victory or defeat in 2015 and to the average Conservative margin in 2015 and 2011. Both graphs show that as the Conservative margin of victory increases, so does support for Scheer. Initially one might see this as concerning for the Conservatives. To win an election, the party needs to reach beyond their base of support and win votes in ridings that they lost in 2015. Electing a leader with support primarily in safe seats could limit their ability to do that.
The upward sloping relationship between Scheer support and Conservative margin of victory is less of a concern if one looks just at the ridings that have a Conservative margin of victory around 0. These are the crucial swing ridings that Conservative have to win if they are to get back into government in 2019. In these ridings Scheer performs remarkably well. The trend line in his support crosses the 50% mark very close to the point at which the Conservative margin of victory goes from positive to negative, suggesting that round half of voters in such ridings preferred Scheer to Bernier. The large number of ridings in and around 0 with respect to the Conservative margin of victory in which Scheer had more than 50% of support on the last ballot also suggests there are a substantial number of close ridings in which Scheer had a great deal of support. While the graphs show that Scheer is more popular in Conservative strongholds than in the rest of the country, they also suggest that he is reasonably popular amongst Conservatives in swing ridings as well.
Bernier’s support follows the opposite trend. The larger the Conservative margin of victory, the worse Bernier did on the final ballot. The trends in both the graph that looks at 2015 and the graph that averages 2015 and 2011 show that Bernier did the best in ridings where the Conservatives did the worst. This may not, however, suggest, that Bernier has a better ability to expand Conservative support to new ridings than Scheer. The ridings in which Bernier did the best are ridings where the Conservatives lost in 2015 and in 2011 by quite large margins. He does ok in the swing ridings clustered around a margin of victory of 0, but there is no indication that he did any better than Scheer. While Bernier is unlikely to alienate Conservatives in swing ridings, it does not appear that he is particularly popular amongst them either.
The strength of Scheer in safe Conservative ridings and swing ridings is confirmed when one looks at average support in both sets of ridings. The two graphs below show the average support for Bernier, Scheer, and a few of the other stronger candidates in ridings where the Conservatives won by at least 10 percentage points in 2015 and in ridings where the Conservatives averaged a 10% percentage point win between the 2015 and 2011 elections. While Bernier led after the first ballot count in both groups of ridings, when he was competing against only Scheer on the final ballot, he lost by an average of just over 10 percentage points.
Bernier did better in swing ridings (defined here as ridings where the margin of victory for the Conservatives was between -10% and 10%), but still lost to Scheer by a substantial margin on the final count. Rather than the gap between the two candidates in these ridings being 10 percentage points, it was 5. These graphs make clear that Bernier was able to make the race for leadership close because of his strong support in ridings that Conservatives lost by substantial margins in 2015 and 2011. In ridings where the Conservatives have strong support, or where the Conservatives where competitive, Scheer was the preferred candidate.
One should take these analyses with a grain of salt. Having strong support amongst Conservatives in a riding does not necessarily mean that a candidate will be able to win over non-Conservative voters in the riding. It will be interesting to see whether Scheer will be able to turn his support in the leadership race in close ridings into support for the Conservatives in the next election. Support in the leadership race, however, should matter to the 2019 election. Leadership candidates have to build organizations in ridings to win votes, sign up new members who they hope will not only support them in the leadership race but in the general election as well, and motivate Conservative supporters to volunteer and to vote in the general election. The results of the leadership race suggest, that when it comes to swing ridings, Scheer is in a slightly better position to do these things than Bernier is.
