David Frum nails Mitt Romney’s problem winning over the public:
Romney has had many fewer abrupt changes of mind than, say, Newt Gingrich, who (you may recall) used to be an environmentalist, among other things. Yet Newt escapes the flip-flopper charge, because whatever view he is expressing at the moment, he expresses ferociously. There’s an old Hollywood saying, “The secret of success is sincerity. Once you can fake that, you’ve got it made.” Romney’s problem is that he cannot fake sincerity. When he panders, people always suspect he knows better – and they blame him for it.
Exactly right. No matter what he says, Romney always comes across as totally insincere, as a used car salesman giving you a pitch.
