If you think Zogby is having a moment of clarity or even capable of one where Obama is concerned, then you don't know anything about Zogby or how the left operates. If he's concerned about Obama failing, it's only because he wants Obama to do more, or he's playing a role in an unfolding narrative. Zogby's entire life has been spent in the molding of public opinion, not in the objective measurement of it. Anything he would express would be part of that effort.
And his statement, that Obama is on the verge of failure, is flatly wrong. Obama has been more successful than any revolutionary marxist could have dreamed. He is on the verge of making the US into a permanently socialist one party state after amnesty, and he will have a spy apparatus that would make Stalin envious to enforce his regime's wishes. What has failed?
