Romney made the prediction on Thursday at an event in Utah, where he is running for the Senate.
Trump would be America's leader for another six years and a half years until he left office after his maximum two terms were up in January 2025.
'I think that not just because of the strong economy and the fact that people are going to see increasingly rising wages,' he said.
'But I think it's also true because I think our Democrat friends are likely to nominate someone who is really out of the mainstream of American thought and will make it easier for a president who's presiding over a growing economy.'
Romney also predicted Trump would 'easily' see off any challenger in the Republican nominations, for the same reasons.
