If the elections were held today and roughly 40% of voters turned out -- a rate typical in recent years -- Gallup's Oct. 7-17 polling suggests Republicans would win 56% of the vote -- 8 points greater than their support from registered voters, and 17 points ahead of Democrats, at 39%. If turnout is significantly higher, Republicans would receive 53% of the vote (a 5-point improvement over their registered-voter figure), and the Democrats, 42%.
The likely voter estimates at both turnout levels have been consistent over the past three weeks.

This Gallop poll is based on registered voters, not likely voters. When likely voters are polled, the difference is larger.
