Mr O Leary's main claim for the Prime Ministership is his alleged ability to get along with and negotiate with Mr Trump. This is utterly irrelevant, as was the charge by Liberals against Mr Harper that he didn't get along with President Obama or the charge by Conservatives that Chretien and Martin didn't get along well with President Bush. Two years after  Canadians elect Harper, Bush is gone and replaced by Obama, and a year after  Canadians elect Trudeau,  Obama is gone and replaced by Trump. Even if O Leary were to become Conservative leader and the Conservatives win the next general election---a rather big "if"---by the time he became PM in late 2019 or 2020, Trump might very well be on the way out.  Canadians need to decide leaders based on their ability to serve Canada's interests, not on their ability to get along with the current President. If the latter were an important criterion, Canada should only holds its elections a few months after American elections.
