I'm late to this, but Mitt Romney has started courting Kentucky Sen. Rand Paul, per Bob Costa:

Sources close to Senator Rand Paul tell National Review Online that Paul and Mitt Romney had a private meeting on Wednesday. Details of the topics discussed are hazy, but Paul — the son of Texas congressman (and presidential candidate) Ron Paul — reportedly found the meeting productive.

The one-on-one conversation in the nation’s capital lasted 30 minutes. Sources say the tone was cordial but it wasn’t meant to be an exchange of pleasantries. The Kentucky Republican focused his questions on policy.
