Ron Paul said Tuesday he was "nibbling" at Mitt Romney's heels.
Soon, Romney may be eating out of Paul's hand.
That's an over-statement to be sure - but it's becoming increasingly clear to those in the Romney camp that something must be done and done soon to build bridges to Paul.
The reason is clear: Romney and his top advisers anticipate a close general election if, as appears likely, he emerges as the GOP nominee. A close general election puts a premium on enthusiasm/turnout and party unity.
