AMERICAN FORK, Utah — Mitt Romney is flashing his familiar smile at city parks and backyards in Utah’s mountains and suburbs, making his final pitch after being forced into a Republican Senate primary Tuesday against a conservative state lawmaker. His opponent has painted him as an outsider who can’t get along with President Trump, but Romney has quieted his once-strident criticism. “I’m not someone who’s going to be a daily commentator on everything the president says by any means, but if there’s something of significance that the president says or does, I feel a moral obligation to express my own view,” he said in an interview at a Utah restaurant where heads turned and people stopped to ask for photos. Romney predicted earlier this month that Trump would win re-election in 2020.
