Sandra Buckler registered as an observer to the Liberal convention in Montreal and was given a pass marked "opposition party."
In fact, Buckler is director of communications for Prime Minister Stephen Harper. You know, the folks who sit in the government benches in the House of Commons.
She's here at the Liberal convention to offer the Conservative view of how things unfold as Liberals pick their leader - and to no doubt stir the pot a bit. Joining her is Dimitris Soudas, Harper's press secretary. He was sporting a button that said "Bob Rae - Harper's choice."
According to Soudas, a few of Rae's Liberals foes have taken to wearing similar buttons as well.
