Tuesday’s election results show Republican candidates should be wary of nationalizing their races and the Trump campaign continues to hemorrhage voters that have long been under the GOP tent, political experts and strategists say.

Though analysts still see President Donald Trump as a formidable candidate as he seeks a second term, some say Republican candidates in suburban areas should resist “nationalizing” their races the way Kentucky Gov. Matt Bevin did. The Republican state chief executive ran as a true Trump Republican — but appears to have lost his reelection bid to Democratic state Attorney General Andy Beshear.

“No one energizes our base like @realDonaldTrump,” Republican National Committee Chairwoman Ronna McDaniel tweeted Tuesday night.

No one energizes our base like @realDonaldTrump. In Kentucky, the governor was down 17 points. President Trump helped lift the entire ticket, winning 5 of 6 statewide races so far! — Ronna McDaniel (@GOPChairwoman) November 6, 2019

Election results from several states Tuesday evening delivered mixed results for Trump and left some scratching their heads about just how long his coattails are going into the 2020 cycle. But he remains an asset to GOP incumbents and candidates in Republican strongholds, they say, meaning the Trump brand could be key in driving up turnout in deeply red counties there and in a handful of swing states.
