Trump’s singular focus on exacting revenge already put one Senate seat at risk.

Six months out from a midterm election in which their majority is at stake, Senate Republicans face a difficult legislative path with a rising number of restless lame-duck senators and a growing sense that the president cares much less about accomplishments that could boost them in November than about protecting himself and settling his political scores.

That power was on full display over the last two weeks, as Trump ousted a string of fellow Republicans he considered apostates for not showing him enough personal fealty.
