About one in five likely voters have yet to solidify their 2010 vote for Congress, including 4% who currently have no preference and 15% who express a preference but say they could change their minds between now and the elections. That is a lower proportion of swing voters than Gallup measured in the prior two midterm elections.
Republican voters are somewhat more committed to their vote choice at this point than are Democratic voters. Among voters who say they would choose the Republican candidate for Congress in their local district if the elections were held today, 86% say they will definitely vote that way, compared with 82% of Democratic voters who are committed to their choice.
