For those who have been paying attention to Canadian politics for the past 3-4 decades, Jean Charest will be a familiar figure.
Charest was first elected to the House of Commons in 1984, he lead the Progressive Conservative Party from 1993-1998, he also served as the 29th premier of Quebec... as a Liberal.
After a 10-year political hiatus, Charest is running for leadership of the Conservative Party of Canada. His past affiliations, and some of his policies, have been touted by his rivals as proof that he's a Liberal in disguise. His chances at winning may hinge on his ability to convince party members otherwise.
So what is Jean Charest's pitch? How do his politics stack up to the likely frontrunner, Pierre Poilievre? And does he actually stand a chance?
