"A new broom sweeps clean"
Well, I know bugger all about Canadian politics - but that is the kind of slogan that makes my blood run cold. Makes me think of Maggie Thatcher. Hell, it makes me think of Adolf Hitler (I'm just talking about the slogan here, remember.)
If any politician is using a slogan like, I'd want to be very very certain indeed I had the same definition of what counts as rubbish as he does before I'd trust him. (Or her - they had this female politician in Australia recently I believe who said things like that...)
