Interesting situation right now at about midnight. 172 needed for a majority, projections say they'll be about 10 short. NDP is projected to get about 10 seats, which might not be enough to bring a Liberal/NDP coalition up to 172. Greens are down to 1 seat, leaving only Conservatives and Bloc Quebecois.
What happens if the Liberals and Conservatives (and Green) can't form a coalition to hit 172. Would the Liberals actually make a coalition with the Bloc Quebecois? What could they agree on? What would the Bloc demand?
