Think it's preposterous that Ron Paul and Mitt Romney are working together? Paul has not attacked Romney once during the GOP debates.
The liberal blog Think Progress broke down the 20 GOP debates so far and finds not one attack from Paul on Romney. In fact, Paul has defended Romney at times.

This is particularly striking given that Paul and Romney do not agree on virtually any policy positions.
Paul has gone beyond merely refraining from attacks. He has actively defended Romney on some of his biggest vulnerabilities. For example, when Rick Perry attacked Romney for “Romneycare” during an October 18 debate, Paul interjected:
First off, you know, the governor of Texas criticized the governor of Massachusetts for “Romneycare,” but he wrote a really fancy letter supporting “Hillarycare.” So we probably ought to ask him about that.
Paul has also run advertisements attacking Romney’s key rivals at critical times. He ran hundreds of thousands of dollars in brutally negative ads attacking Gingrich in Iowa. Paul now is using his scarce funds on a television ad attacking Rick Santorum in Michigan, a key state where Paul is a non-factor.
