One-third of voters remain undecided

One third of congressional voters remain up for grabs ahead of Election Day, according to a new AP-GfK poll--an unusually high number that reflects other polls showing a lack of voter enthusiasm across the country.

The AP-GfK survey found one-third of respondents saying either that they hadn't settled yet on a candidate in the 2010 cycle, or that they were still open to switching from the congressional hopeful who had provisionally won their support.

Candidates themselves have begun to openly concede that voters are fed up this season. Meg Whitman, the Republican nominee for governor of California, says in the opening sentence of her latest campaign ad: "I know many of you see this election as an unhappy choice."

You can watch Whitman's commercial below:

A pervasive lack of voter enthusiasm has helped keep voters, especially Democrats, on the fence this year. In 2008, by contrast, "persuadable voters" made up just 14 percent of the electorate surveyed at this time of year.

Though both parties could regard these "persuadable voters" as an opportunity, it appears that the GOP is in a better position to recruit them. Forty-five percent of persuadable voters in the survey "tentatively prefer" their Republican House candidate while 38 percent prefer the Democrat.
