Joe Cressy, The NDP, And Keystone XL

NDP candidate Joe Cressy is yakking it up at the #trinspa debate:

Cressy: stop subsidizing oil patch, and start green energy; stop the Keystone XL pipeline, etc. #trinspa

You know we all hate Keystone here in T.O. but I don't see what making it front-and-center in their campaign is going to do for the NDP.  What practical effect does opposing a pipeline the fate of which will be decided by the government of another country have?  The entire party might as well drop its pants are fart in the direction of Washington.  It'll do as much good.  What victory can be claimed if the decision goes against Keystone?  Could they not settle on  issues that apply to Trinity-Spadina  specifically?
