An NPR poll looks at the Congressional battleground states:
The results are a wake-up call for Democrats whose loses in the House could well exceed 30 seats. In the named-congressional ballot in the 60 Democratic districts, Democrats trail their Republican opponent, 42 to 47 percent, with only a third saying they want to vote to reelect their member. In the top tier of 30 most competitive seats, the Democratic candidate trails by 9 points (39 to 48 percent) and by 2 points in the next tier of 30 seats (45 to 47 percent). On the other hand, the Republican candidates are running well ahead in their most competitive seats ( 53 to 37 percent). As we saw in the special election in PA-12, Democrats will have to battle on a seat-by-seat basis — that has shifted these kinds of numbers this year.
The effort by individual campaigns will have to push against walls that seem very hard to move at this point. We tested Democratic and Republican arguments on the economy, health care, financial reform and the big picture for the 2010 election. The results consistently favored the Republicans and closely resembled the vote breakdown. Democrats are hurt by a combined lack of enthusiasm and an anti-incumbent tone.
The PA-12 special election showed that Democrats can localize a race and win against strong headwinds, but you can't count on winning through superior candidates or political tactics everywhere.
