Romney should be doing a walk of shame today, after reversing most of his irresponsible, hawkish foreign policy statements from the last year just to have a hot night with undecided female voters in the final debate. How does he live with himself?But I’m having a hard time watching television coverage of Romney’s debate performance the morning after. The conventional wisdom seems to be that while President Obama won the debate, Romney’s “prevent defense” at least kept him in the race – and it was the politically wise course. Of course, Obama’s “prevent defense” two weeks ago in Denver was a debacle that changed everything. I’m not sure why Romney’s turn at it is supposed to be smarter politics.
