Republicans are just over six months away from the 2018 midterm elections, and there’s plenty to worry about. Midterms almost always favor the party out of power, and Democratic voters are far more enthused about the coming elections than their Republican correlatives. And although one should never underestimate the present-day Democratic party’s ability to wreck an easy win, the likelihood is that Republicans will lose the House, and they may lose the Senate, too. Such an outcome could well mean Donald Trump’s being impeached.

The one thing going decisively in Republicans’ favor is the economy. The jobless rate has dropped to 4.1 percent and may drop further, GDP growth seems certain to remain at around 3 percent, and wages are rising across the board.
