Will Wilkinson won't rule out the possibility:
Mr Romney may have failed last week to satisfy wonkish politics junkies, but his federalist case for state experimentation in health-care policy sounds both sensible and conservative—at least if one doesn't push on it too hard, and most voters won't. Perhaps most importantly, when he talks about this issue, he comes off as an impressively capable man. It seems too early to say for certain that it's beyond Mr Romney's considerable powers to bluster his way past this issue and sell Republican voters on the idea that he's the electable turnaround artist America needs.
