OTTAWA — The fact that a party running under the Liberal banner pulled off a decisive win in Monday’s New Brunswick election seemed to put a spring in the step of at least a few Liberal MPs, even as they headed into a tense caucus meeting on Wednesday morning.

“Go Susan Holt!” one Liberal MP shouted as she filed into the West Block of Parliament Hill for the meeting, pumping her fist in the air, referring to the victorious New Brunswick Liberal leader.
