The two candidates have accused Romney of betraying the Republican Party, dismissing his views as inconsequential.
Ramaswamy, in a statement to Fox News, criticized Romney's stance, stating, "Turns out he's opposed to America-First itself, not just one man."
He added, "Newsflash, Mitt: I didn't vote for you either, and I still call on your niece Ronna [McDaniel] to resign."
A representative from Trump's campaign was equally dismissive of Romney's comments, stating, "Voters aren't going to take advice from a loser and quitter like Mittens."
Romney's controversial remarks were made during an interview with CBS' Norah O'Donnell. When questioned about his preferred Republican candidate, the Utah senator initially responded with "anybody," expressing his willingness to support any Republican candidate. However, he later singled out Ramaswamy as an exception.
Romney further suggested that he would be open to voting for several Democrats, considering them an improvement over Trump and possibly even current President Joe Biden. He did, however, express some admiration for Biden, describing him as "a very charming, engaging person." Despite this, Romney expressed disagreement with Biden on most issues, criticizing his numerous mistakes.
Romney concluded his interview by expressing his desire for a new face to lead the Democrats. This is not the first time Romney has voiced his disapproval of Trump. Prior to his retirement announcement in September, he cited the likelihood of either Trump or Biden being the next president as a factor in his decision to step down. He criticized Biden's leadership abilities and Trump's unwillingness to lead on important matters.
Trump has not been shy about expressing his disdain for Romney, celebrating the senator's retirement as "fantastic news for America, the great state of Utah, and for the Republican Party."
