The bigger “wave” came AFTER the last ballots cast. It is funny how that worked. I think 2020 is the end of the Republican Party as a major party as the Democrats cheated,lied,fought dirty, and evolved to eye wash American voter idiots.The GOP has no gumption and is merely DNC lite.
In 2020 the house will probably be all leftists. The (R) fools don’t deserve a win & only 43 members voted for a true conservative for House leader.
