Mitt Romney says what other Republicans won't: He's not voting Trump

Sen. Mitt Romney of Utah crossed a line this week that few if any national Republican officials have broached: rejecting Donald Trump at the ballot box if Trump's the nominee.

Asked by CNN's Kaitlin Collins whether he would vote for Trump over Joe Biden, Romney was unequivocal. 

"No, no, no, absolutely not," he said. Romney explained that whether he aligned with Trump on policy was not his primary consideration.

Instead, he placed character above all and said that having a president who was so "defaulted" of character would undermine America's greatness and our ability to be an international leader.
