GOP Takes Unprecedented 10-Point Lead on Generic Ballot

The last Gallup weekly generic ballot average before Labor Day underscores the fast-evolving conventional wisdom that the GOP is poised to make significant gains in this fall’s midterm congressional elections. Gallup’s generic ballot has historically proven an excellent predictor of the national vote for Congress, and the national vote in turn is an excellent predictor of House seats won and lost. Republicans’ presumed turnout advantage, combined with their current 10-point registered-voter lead, suggests the potential for a major “wave” election in which the Republicans gain a large number of seats from the Democrats and in the process take back control of the House. One cautionary note: Democrats moved ahead in Gallup’s generic ballot for several weeks earlier this summer, showing that change is possible between now and Election Day.
