That said, Carleton shouldn't flip to the Liberals (a rare pickup opportunity) unless the Trillium Party runs a strong candidate, and that candidate gets a decent chunk of the vote. But if Trillium runs well in the rural parts, and the Liberals decide they want a hedge against losses elsewhere, they might be able to snare away at the Red Tory types in the suburban portions...
