There is a sense among many Conservatives that the race may turn into a coronation for Peter MacKay, although Erin O’Toole may have something to say about that.

Yet even he may feel pressure to stand down. Colin Carrie, the Conservative MP for Oshawa, is the latest caucus member who supported O’Toole last time to come out in support of MacKay as the best person to “unify, modernize and strengthen” the party. Another of MacKay’s former colleagues, Pierre Paul-Hus, came out Thursday to endorse him – support that may prove crucial in the Quebec City area.
