Among the many findings in the latest CBS News/New York Times poll is this nugget:

A majority of likely voters say their House vote is a referendum on President Obama, and more are voting against the president than for him. Thirty-two percent are casting a vote against Mr. Obama, while 22 percent are casting their vote to support him. Forty-two percent say their vote is about something else.

The president has been traveling the country to stump for candidates ahead of the midterms, but it may not be much help: a majority of likely voters (56 percent) say Mr. Obama’s support for a candidate has no impact on their vote. And while 14 percent say Mr. Obama’s support makes them more likely to back a candidate, 29 percent say it makes then less likely to do so.

That’s gotta hurt someone who ran on the strength of his personality, how lousy the other guy’s party was, and not much else.
