Washington (CNN) - A CNN Poll of Polls compiled and released Friday indicates that 50 percent of likely voters would choose a Republican candidate for Congress if the election were held today, with 42 percent saying they would vote for a Democrat.
Eleven days before the election, Republicans continue to poll ahead of Democrats when voters are asked whom they would choose for Congress on election day. The Republican margin has increased one percentage point since the last CNN Poll of Polls, from a seven point margin to an eight point margin, which is virtually identical to the previous survey.
This newest edition of the CNN Poll of Polls is an average of three national surveys conducted during the from October 13-18 : Pew Research (October 13-18), AP-GfK (October 13-18), and NBC/WSJ (October 14-18). The Poll of Polls does not have a sampling error.
The generic ballot question asks respondents if they would vote for a Democrat or Republican in their congressional district, without naming any specific candidates. It is used by many polling organizations, including CNN/Opinion Research Corporation surveys. In the battle for control of Congress, the generic ballot is arguably the most watched polling indicator, but it should not be considered a one-for-all.
