There is no one currently in the Conservative party who has the credentials to step forward as a credible candidate for PM. The influx of Reform Party people have skewed the party so far to the right that it is in danger of being mistaken for the GOP. Singh is both credible and articulate but I do not think Canada is ready for a practicing, observant Sikh as prime minister. Trudeau has made some politically bad decisions, and this is on him and his advisors, but none of them are criminal, so far as I know. When the Conservatives were able to have credible leaders like Joe Clark and Bob Stanfield, they were a legitimate alternative, but all that changed with Mulroney. His administration new lows for corrupt behaviours and all but destroyed the PC party, forcing them into a shotgun marriage. There are good people in all three parties but, but sad to say, our expectations of our politicians has been lowered.
