Sorry, we've been hearing that since before Trump clinched the nomination in 2016, but political parties change, and there's no enduring Republican norm that is going to imminently reassert itself. I do know some "decent Republicans," though they've been voting Democratic for a while now. When I was growing up in the 1980s and 1990s, a lot of people saw the Republican Party as a party of educated, foreign policy-savvy, business friendly elite pragmatists. For some people I know, that brand is cemented in their minds as the soul of the Republican Party, regardless of 30+ years of various radically different factions dominating the party since then.

But now those "decent Republicans" vote Democrat. Their feeling about it, to repurpose a saying from a different context, could be summed up as, "We didn't cross the border, the border crossed us." They never wanted to be Democrats and still have a sentimental attachment to the Republican Party, but here they are.
