Mitt Romney has decided the best defense is a good offense. Derided as a "flip-flopper" by President Obama? Throw the charge back in the president's face. Attacked for his plan to revamp Medicare? Fire back that Obama has already crippled the popular entitlement program.
That was the central theme of the all-but-inevitable Republican presidential nominee's speech Wednesday to the Newspaper Association of America: Try to take evident vulnerabilities of his own candidacy and turn them against the current White House occupant. As Romney pivots toward the general election - and after Tuesday's victories, this week seems to mark a line of demarcation between the primary and general elections - it hints at a major part of his strategy to unseat Obama.
