WHEN Mitt Romney was governor of liberal Massachusetts, he supported  abortion, gun control, tackling climate change and a requirement that  everyone should buy health insurance, backed up with generous subsidies  for those who could not afford it. Now, as he prepares to fly to Tampa  to accept the Republican Party’s nomination for president on August  30th, he opposes all those things. A year ago he favoured keeping income  taxes at their current levels; now he wants to slash them for  everybody, with the rate falling from 35% to 28% for the richest  Americans.
All politicians flip-flop from time to time; but Mr Romney could win an  Olympic medal in it (see article). And that is a pity, because this  newspaper finds much to like in the history of this uncharismatic but  dogged man, from his obvious business acumen to the way he worked across  the political aisle as governor to get health reform passed and the  state budget deficit down. We share many of his views about the  excessive growth of regulation and of the state in general in America,  and the effect that this has on investment, productivity and growth.  After four years of soaring oratory and intermittent reforms, why not  bring in a more businesslike figure who might start fixing the problems  with America’s finances?
Mr Romney may calculate that it is best to keep quiet: the faltering  economy will drive voters towards him. It is more likely, however, that  his evasiveness will erode his main  competitive advantage. A businessman without a credible plan to fix a  problem stops being a credible businessman. So does a businessman who  tells you one thing at breakfast and the opposite at supper. Indeed, all  this underlines the main doubt: nobody knows who this strange man  really is. It is half a decade since he ran something. Why won’t he talk  about his business career openly? Why has he been so reluctant to  disclose his tax returns? How can a leader change tack so often? Where  does he really want to take the world’s most powerful country?
It is not too late for Mr Romney to show America’s voters that he is a  man who can lead his party rather than be led by it. But he has a lot of  questions to answer in Tampa.
