The Pollcast: Pipeline problems and an NDP-Green squabble

If the Liberals were hoping for some good news this past week, the Federal Court of Appeal didn't help them when it ruled it wouldhear appeals from opponents of the government's Trans Mountain pipeline expansion project.

And while the Greens thought they were getting good news from a bevy of defectors from the NDP in New Brunswick, it turns out things might not be as simple as they seemed.

Opponents of Trans Mountain cheered the court's ruling, forcing the Liberals to defend their approach to the project. While this might not delay work on the project (which has started already),it could providefurther ammunition to people who doubt the Liberals' sincerity on this file.

Doubt was also cast on the Greens this week, afterit was announced that 14 New Democrats in New Brunswick were jumping ship from the NDP to the Green Party. Turns outsome of those New Democrats hadn't agreed to be included on that list. But the squabble between the NDP and Greens highlights the fight these two parties are in for third place a fight only the Greens are happy to be fighting.
