Obama Rejected Keystone Pipeline For Political Reasons

That well known winger, Joe Nocera:

I realize that President Obama rejected Keystone because, politically, he had no choice. My guess is that, in his centrist heart of hearts, the president wanted to approve it. But to give the go-ahead before the election was to risk losing the support of the environmentalists who make up an important part of his base.

If true, it's nearly an act of treason. You don't go against the interests of the nation to further your re-election.  If this is half time, take out out the quarterback.
