Harper was happy to smear Paul Martin, even giddy beyond belief to smear Stephane Dion, but I still don't see how he can possibly risk the blowback of trying to smear Michael Ignatieff.
Harper was able to snipe at Martin and poke sticks into Dion's side from a position where he was pretty much safe from retaliation. There's no longer any safe place where Harper can hide.
Want to look into Ignatieff's past? Good luck with that. It's L'il Stevie who's got the problem with his past now and that he's got in spades.
Harper came into politics literally cloaked in self-righteousness and smug, uber-conservatism. Canada was a northern European welfare state. Kyoto was a socialist plot to steal from the rich. Afghanistan was where we drew the line to defeat Islamist terrorism.
Harper has literally abandoned just about every position he once stood for and promised to uphold. Accountability? Transparency? You name it, he's ditched it. Stephen Harper has turned himself inside out in his quest to cling to power.
Poor old Boss Harp. He's messed himself up so badly that he can't take a swing at Iggy without clobbering himself in the process. Let the games begin.
