ANALYSIS — Are we still headed for a Democratic wave in the House next month? That all depends on how you define a wave. But one thing is clear: Democrats are still likely to flip the chamber even after all the buzz about a post-Kavanaugh Republican bounce.
A wave occurs when a large number of one party’s seats flip to the other party, invariably because of a national political figure (the president, usually) or a national issue. Many competitive seats change hands, and at least a few entrenched incumbents suddenly find themselves in trouble.
