last night was Bono at the Liberal Party Coro… er, Convention supporting Paul Martin. It’s way too early to know precisely if it has much significance beyond Bono’s star power, but there is a possibility that having a rock-star activist in such a prominent slot in the convention is intended to communicate that Martin isn’t necessarily going to be the conservative many are expecting. Just as likely, though, it was designed as a high-profile placebo. Only time will tell.
