Sen. Susan Collins, R-Maine, who said this week she will not vote for Donald Trump or Hillary Clinton, will instead write in a name on her ballot this fall.

"I'm probably going to end up writing in the name of someone," Collins told CNN Wednesday morning. "And I never would have guessed I'd be in that situation."

When asked by Cuomo who she will write in — including her own name — Collins offered former Florida Gov. Jeb Bush, who she had first endorsed in the primary before he dropped his race.

Collins also offered former Secretary of State Condoleezza Rice.

"[I]'ve always been a fan and she certainly would know how to handle the dangerous world that we're living in in a way that Donald Trump does not," she explained.

Collins said she hadn't quite decided yet, but those are the two names at the top of her list.

On Monday, Collins, who has been in the Senate since 1997, said she is not going to vote for Trump.

"I will not be voting for Donald Trump for president. This is not a decision I make lightly, for I am a lifelong Republican. But Donald Trump does not reflect historical Republican values nor the inclusive approach to governing that is critical to healing the divisions in our country," she wrote in an op-ed for the Washington Post.
