I haven't heard this mentioned in any of the coverage of yesterday's LPoC leadership debate, but on February 26th MHF was for Northern Gateway Pipeline; as of yesterday's debate, she's sudddenly agin it. That's what you call a policy reversal...a waffle...a dither...a flip flop, even.
Worth noting too that among the contenders only Joyce Murray has come out against Kinder Morgan in addition to the NGP. Joyce is a B.C. gal, and I'm assuming her opposition is a sign of which way the winds are blowing out on the left coast over that project.
