Abacus Data (Federal - Sept. 14-18, 2012)
Conservative: 35% (-2%) - 157 seats
New Democratic: 35% (+3%) - 140 seats
Liberal Party: 17% (-3%) - 28 seats
Bloc Québécois (QC Only): 30% (+5%) - 13 seats
Green Party: 6% (=) - 1 seat
This isn't a great poll for the Liberals, and that's pretty obvious (that's a funny trait of Abacus, the Liberals are almost always lower with their polls). But the other parties do well enough; the Conservatives retain a healthy advantage in Ontario (41% to the NDP's 30%), meaning that they'll keep more seats so long as the NDP fail to get close to them. The NDP is down slightly in Quebec, with a nine-point advantage over the Bloc.
I've noticed that the Bloc has actually been bumped up in every poll since Marois' election - maybe signs that if the provincial PQ government does well, the Bloc may start to pick up some support as well? I'm not sure, but its a trend to keep your eyes on.
