Instead of trashing conservatives, you might want to remember how many of them voted Liberal because they despised Harper as much as you lefties.

In my case, living at the time in Niagara Falls, Ontario, I was forced to vote NDP. I'm as conservative as they come, but no way would I vote for Rob Nicholson. 

The Conservative Party needed a time-out to rebuild. It wouldn't happen on its own if Harper was re-elected. If Kevin O'Leary becomes leader, that rebuilding is done. The opinion of Liberals and other socialists is irrelevant. 

And I've got more bad news for you: Most Liberals are not far-left, big-spending socialists like your Trudeau friend. So where do you think they're going to go when the next election comes around and Kevin O'Leary is leader of the Conservatives? That's right!
