MUST WATCH: Mitt Romney says he’ll vote Democrat over Trump or Vivek

In an interview with CBS's Norah O'Donnell, Romney said he would be "happy to support any one of the Republicans," he stressed, "maybe not Vivek, but the others that are running would be acceptable to me."

"I'd be happy to vote for a number of the Democrats too," Romney added. "I mean, would be an upgrade from, in my opinion, from Donald Trump, and perhaps also from Joe Biden."

The Senator then clarified that he likes President Biden. He said, "I find him a very charming, engaging person." Romney continued, "In some places, I agree with him, but in most places, I disagree with him. I think he has made all sorts of mistakes."

"I would like to see someone else run," he concluded about Biden.

News that Romney would not support former President Trump is nothing new in the long feud between the two. In 2020 and 2021, Romney was one of the few Republicans to vote to impeach Trump.

In September, Romney announced that he would not seek re-election for his Senate seat. "The next generation of leaders must take America to the next stage of global leadership," he said.

In a phone interview with the Washington Post, before his announcement, Romney said the decision was influenced by his age, 76, but also because "we’re probably going to have either Trump or Biden as our next president." He added, "Biden is unable to lead on important matters and Trump is unwilling to lead on important matters.”

Upon hearing the news of Romney's decision, former President Trump said it was "Fantastic news for America, the great state of Utah, and for the Republican Party." He added, "Mitt Romney, sometimes referred to as Pierre Delecto, will not be seeking a second term in the US Senate, where he did not serve with distinction."

Romney was the GOP nominee for president in 2012, where he lost to then-incumbent Barack Obama. In 2019, he was elected to the US Senate and will finish his term in 2025.
