Democrats woke up Thursday to some gloomy post-Christmas news: they have fallen behind Republicans in the battle to win House and Senate seats in the 2014 election.

A new CNN/ORC International poll released Thursday shows Republicans holding a 49 percent to 44 percent edge over Democrats in the “generic ballot,” which asks registered voters whether they would choose a Democrat or a Republican in the midterm elections without identifying specific candidates.

Just two months ago, after the government shutdown, Democrats were up 50 percent to 42 percent. But a month later, the GOP had a narrow edge - 49 percent to 47 percent. The dramatic shift in the political landscape follows the rollout of the federal insurance exchanges, which have been plagued by technical troubles.
