“Presidents lead by offering a vision for the country rooted in certain principles, not by promising a technocracy that runs on “data.” Mr. Romney’s highest principle seems to be faith in his own expertise.

“More immediately for his Republican candidacy, the debate over ObamaCare and the larger entitlement state may be the central question of the 2012 election. On that question, Mr. Romney is compromised and not credible. If he does not change his message, he might as well try to knock off Joe Biden and get on the Obama ticket.”
