My colleague, Ed, the more handsome one in our caricature, was sure right about the impact gas prices would have on President Obama. Despite positive economic news and continued bad news for the Republicans, the polls seem to have taken a dip for the president recently.

The most recent serious poll, the Washington Post-ABC survey, showed the president's favorable ratings dropping outside the margin of error. Four bucks a gallon gas is taking its toll.

On some level, there may be nothing surprising about this development; gas prices have intermittently taken their toll on presidents' poll ratings since Jimmy Carter, and recession-whacked Americans are especially sensitive these days to further pocketbook burdens.

But Obama's dip does show his basic weakness. Like our economic recovery, Obama's political recovery is only one new problem away from faltering. It's going to be a long year.
