Gallup's generic ballot for Congress among registered voters currently shows Republicans with 46% of the vote and Democrats with 43%, similar to the 46% to 46% tie reported a week ago. However, in Gallup's first estimates among likely voters, based on polling from Sept. 23-Oct. 3, Republicans have a double-digit advantage under two separate turnout scenarios.
Here's what Gallup found:
Registered Voters: Dems 43% Reps 46%
Likely Voters-High Turnout: Dems 40% Reps 53%
Likely Voters-Low Turnout: Dems 38% Reps 56%
