This is entirely a large factor. The NDP is now viable in former Liberal ridings such as Toronto—St. Paul's, LaSalle–Émard–Verdun, and Ottawa-Centre. Why would the NDP keep propping the Liberals up in power when a Conservative majority is essentially guaranteed (and that's not going to change in 10 months), and they have a chance to exploit Liberal weaknesses? People that want to stall the inevitable are deluding themselves if they think things will massively turn around in the span of half a year when so many Canadians have lost confidence in the governing party.
