Former Congressman Vin Weber (R-Minnesota), who served as Romney's policy chairman in 2008 and as "special adviser on policy" in 2012, criticized Romney during a Bloomberg Politics interview on Thursday.
"I'm not happy, frankly, with the way he's chosen to re-enter presidential
Weber went on to praise Romney's character but suggested former presidential candidates need to let fresher faces step forward.
"He's a great man. He would be a great president, but there's not a lot of good precedent for somebody losing the election and coming back four years late and becoming the nominee. Thomas Dewey is the best example in our party - didn't work out too well," Weber continued.
Weber's remarks echo many other Republican activists who say they're not pleased with Romney's potential return to the presidential race.
Romney, a former Massachusetts governor, repeatedly insisted he would not run in 2016 but backed off that pledge at the end of last week and said he was seriously considering another campaign.
