Paul Says He Would Have Trouble Backing GOP Rivals

Ron Paul says he might not support his rivals for the Republican presidential nomination.

In an interview Friday with Bloomberg News, the Texas congressman said the other GOP contenders represent the "status quo" and do not differ much from Democrats.

Paul says he would have trouble backing any of them and wants to wait and see if they adopt any of his priorities, such as auditing the Federal Reserve.

Paul and Mitt Romney are leading most polls ahead of Iowa's kickoff caucuses. Paul has attracted support from a coalition of tea party supporters, students and independents.

Paul says Romney's business background makes him more suited for the presidency than Newt Gingrich. The former House speaker has said he couldn't vote for Paul if he became the Republican nominee.
