Just before eight o’clock in the morning on Wednesday, the Republican congressman Adam Kinzinger typed out a gleeful tweet. A few hours earlier, his party’s candidate in the U.S. Senate race in Alabama had gone down to defeat, and Kinzinger couldn’t have been happier—or clearer about who was to blame. A thirty-nine-year-old military veteran from a suburban Illinois congressional district, Kinzinger was used to feeling aggrieved about Steve Bannon and his self-styled Republican revolutionaries. Now that Bannon’s backing of Roy Moore had backfired spectacularly in one of the nation’s most Republican states, Kinzinger tweeted some of that grief right back at him.

“Bannon is a RINO,” Kinzinger tapped out, using the favored conservative insult for “Republican in name only.” “His morally inept strategies are unwelcome here. #YoureFired.”

All day, he got thousands of likes and retweets. One of his commenters was Jeb Bush’s son, Jeb Bush, Jr. “Thank you for your leadership Adam!” he enthused.
