Although Bevin was controversial and widely disliked, he was also a devotee of the president, embracing Trump’s agenda and his anti-establishment persona. And in the contest’s final days, Bevin sought to cast his candidacy as a bulwark against House Democrats’ impeachment inquiry of Trump.

But Bevin’s attempt to nationalize his cause by stoking conservative grievances about the impeachment process was not enough to overcome his problems nor was Trump’s raucous rally for the governor on Monday — raising questions about Trump’s political strength as he faces a barrage of challenges and a difficult path to reelection.

The outcome — with Democrat Andy Beshear claiming victory with a lead of several thousand votes and Bevin refusing to concede — underscored how Republicans are struggling to navigate choppy political waters as the 2020 campaign now begins in earnest. Trump continues to dominate the party, but many lawmakers are uneasy about their ability to defend his conduct and hold on to suburban support.

Yet few Republicans are willing to even lightly criticize Trump because they widely believe they will need his voters’ backing and enthusiasm in order to survive next year.
