You don't know 71% of independent economists leaned Obama.
71% of self-identified independent NBER economists, who work in academia, out of those who purposefully chose to respond to this survey and mail it back in, 44 out of 62 leaned obama.
As usual, you are swinging at strawmen.
I don't disagree with your point and never have. It's merely a survey with limited responses and nobody... is claiming it represents ALL economists and such. This is your own paranoid strawman argument.
