Two months ago, Democrats held a 50%-42% advantage among registered voters in a generic ballot, which asked respondents to choose between a Democrat or Republican in their congressional district without identifying the candidates. That result came after congressional Republicans appeared to overplay their hand in the bitter fight over the federal government shutdown and the debt ceiling.
But the Democratic lead evaporated, and a CNN poll a month ago indicated the GOP holding a 49%-47% lead. The new survey, conducted in mid-December, indicates Republicans with a 49%-44% edge over the Democrats.
Democratic voters seem particularly unenthusiastic about voting, and that is likely to benefit the GOP. Thirty-six percent of Republicans say they're extremely or very enthusiastic about voting. That number drops to 22% among Democrats.
Another GOP advantage is the President's standing with the public: 55% of registered voters say that they are more likely to vote for a congressional candidate who opposes the President than one who supports him and four in 10 say they are likely to vote for a candidate who supports Obama.
