Vancouver Mayor Gregor Robertson says a video that allegedly shows Toronto Mayor Rob Ford smoking crack is "a big distraction."

Robertson was speaking at Moving the Future, a Metro Vancouver conference about transportation and the economy.

"We need to be focusing on priorities that make a difference for everyone who we represent. And the personal misgivings are really unfortunate when it's all about that. It's not good for democracy. It's not good for the community," says Robertson.

Ford says he has no reason to resign, and Richard Johnston, Canada Research Chair in Public Opinion, Elections and Representation at UBC, agrees he may weather this storm.

"I think it's pretty clear [Rob Ford] has no shame," says Johnston, "And that's part of his in-your-face persona which, to a certain extent, got him where he is now."

"Now, crack," Johnston laughs, "That's criminal. On the other hand, it's a crime without victims in some sense."

Ford's future may depend less on his personal life, and more on his ability as a politician, Johnston says.

"You have the sense that his coalition is kinda coming apart. Candidates are going to be challenging him from the right. And so, he may have done himself in."
