When Gov. Glenn Youngkin of Virginia found out that Republican research had linked the G.O.P.’s nominee for lieutenant governor to a blog featuring photos of naked men, he tried to save his party from an embarrassing situation.

Mr. Youngkin called the candidate, John Reid, a longtime conservative talk radio host in Richmond, and told him he needed to abandon his campaign because the website was certain to be discovered and would tank the party’s entire ticket.

“I need you to drop out,” Mr. Youngkin said, according to two people briefed on the call.

Then a funny thing happened. Mr. Reid did not quit. Instead, he posted a five-minute video to social media noting that he is gay and explaining that he had watched pornography and had one-night stands in the past. The Republican base in Virginia quickly rallied around him.

The episode has illustrated the post-shame nature of Trump-era politics in a state where one recent governor survived a blackface scandal; another was convicted on corruption charges (which the Supreme Court subsequently threw out); and, just two years ago, a state legislative candidate stayed in her race even after the emergence of live-streamed videos of her having sex with her husband.

It also revealed a stunning lack of political juice from Mr. Youngkin, who has been considered a potential Republican presidential candidate since the day he won election as governor in 2021. A wealthy former private equity executive, he is widely credited with saving Virginia Republicans from oblivion and, since his victory, has rebuilt and funded much of the state party.
