Alabama voters can, of course, elect whomever they choose. Pigasus, a 145-pound hog, was once nominated as president by the Youth International Party as part of a protest outside the 1968 Democratic National Convention, so an electoral preference for swine is not wholly unprecedented. But Mr. Trump and the GOP have no business embracing him, let alone accepting him into the Senate, whether he’s the 52nd vote in their caucus or the 99th. With this turnabout, Republicans are essentially broadcasting to the country that they are all-in with President Trump, not just in regards to his politics and his populism, but to his serial lying and his boasts about sexual predation. This is a shameful moment for the Party of Lincoln, now the Party of Look The Other Way. Even Mr. McConnell, who once upon a time played a leading role in drumming Bob Packwood out of the Senate, has now promised to “swear in whoever’s elected.” So much for believing women.
