Mitt Romney said it, because he Feels it
Romney hates Trump. It colors his view, which is that; Trump is a disaster. I can’t explain his (extreme?) views any better than Romney did today in a speech that captured everything I’m thinking/worried/excited about Donald Trump and this country’s place in time and history both economically and geo-politically.
Watch the speech. If you’re a Romney fan, the message is — Fight this Trump madness, talk to your Trump supporter friends, stage an intervention, save America. But, Romney hates Trump, it colors his view.
