Presidential poll numbers are hurting Democrats

President Obama is dragging down his party and hurting the prospects of fellow Democrats as they head into midterm elections that will determine who controls Congress, according to a new McClatchy-Marist poll.

Just 40 percent of voters approve of the way he's doing his job, tying his worst mark in three years and the second worst of his presidency. Just 39 percent approve of the way he's dealing with the economy and only 33 percent approve of how he's dealing with foreign policy, the worst of his years in office.

By 42 percent to 32 percent, voters say their opinions of Obama make them more likely to vote this fall for a Republican than for a Democrat.
