Donald Trump finally made some bold and provocative claims that were largely true, and the Republican Party finally closed ranks to attack him.
Saying Mexican immigrants are rapists didn't do it. Calling for a return of torture didn't do it. Calling for a ban on Muslim immigration didn't do it. Raising questions about Barack Obama's status as an American citizen didn't do it. Pretending that thousands of Muslims in New Jersey cheered 9/11 didn't do it.
So what did? Trump said that invading Iraq was a disaster, that the country was misled into invading Iraq by the Bush administration, and that the claim that Bush kept the country safe from terrorism is ridiculous because 9/11 happened on his watch.
