ATLANTA — Michael Pemberton, a 65-year-old conservative from Kentucky, started the day in a good mood. He was attending his second RedState Gathering, and ready to hear from 10 of the Republican Party's presidential candidates. He dug into breakfast — coffee and fruit — and sat down with another conference-goer.

"One of the chaps across me asked, 'Did you hear the news?'" recalled Pemberton. "I thought he was going to tell me that a sinkhole opened up in Kentucky and I couldn't go again. But no: He said, they disinvited Donald Trump. I lost my appetite."

The TV news confirmed it. RedState's outgoing editor-in-chief, Erick Erickson, made an 11th hour call to disinvite Trump after the GOP presidential front-runner told CNN that Fox News's Megyn Kelly had "blood coming out of her eyes, blood coming out of her wherever" when she grilled him during Thursday's presidential debate.

Pemberton grabbed a sharpie and a note card and scrawled out "I AM DONALD TRUMP." He affixed it to his jacket with an American flag pin and grudgingly walked into the conference, determined never to come again.

More than 700 activists had signed up for the gathering, and up to a thousand of them had been expected to join Trump at a Saturday night party at the College Football Hall of Fame. On Saturday morning, the reaction to Trump's exclusion was mixed — and distracting. Annoyance at what seemed to be a politically correct purge competed with annoyance at Trump himself.

"It was really inappropriate to attack Megyn Kelly," said Richard Fonte, 70, an activist who split his time between Texas and Illinois, and strongly supported Gov. Scott Walker (R-Wis.) for president. "That and the fact that he's taking the position that he might run as a third party — that would automatically elect Hillary Clinton."

Fonte's wife, Dulsey, 68, was even happier to see Trump gone: "I find him crude," she said. "I have no sympathy for his candidacy."
