Congress may be headed for an Election Day double flip.
With less than four weeks to go, Republicans appear poised to win the Senate, which is currently controlled by the Democrats. The Democrats, meanwhile, seem to have a slight edge in the race for the Republican-controlled House.
If the polls and predictions prove right — and that is still a big if — it would be the first such flip, a historic and fitting outcome for a political era marked by slim margins and deep division.
A scenario where voters flip the majorities in both the House and Senate, but in opposite partisan directions, could lead to gridlock as a new president attempts to govern next year. Congress faces crucial deadlines to fund the government and avoid defaulting on federal debt in coming weeks. Narrow, divided majorities in Congress could make meeting them far more difficult.
