This week a key political data point tipped for the first time in 16 months. In November 2009, the Talkingpointsmemo composite poll of generic Congressional preferences showed more voters wanted Republican control of Congress than Democratic.
But for the first time since November 2009, the Democratic Party took a small lead over the Republican party in Congressional polls, according to the Talkingpointsmemo composite poll tracker.
The latest results show 42.4% of voters would vote for a Democratic candidate for Congress, while 42.2% prefer a Republican candidate. The Republican advantage had recently been consistently around plus 6%.
As is normally the case in national elections, about 15% of voters in the middle will decide whether Minority Leader Pelosi becomes Speaker Pelosi one more time in January 2013.
