I have seen a Klinton ad for Obama too and it does send mixed messages: it implies that Klinton did a good job in his presidency and that Obama has not.
Regardless, this is a poor article. Reason for Obama crashing is that he has done a terrible job in office, the worst since Carter.
one of the most disturbing things about this election is the rehabilitating of both Clintons into some saint like figures/ I refuse to think of them as any thing other than two of the most degenerate politicians of our time. Also laughable that a guy that never got 50% of the American electorate to vote for him in either election is giving advice.
