Ron Paul explains why he won't quit in an interview with CNN

With just months to go until the 2012 presidential election, all of Mitt Romney's former presidential rivals are now backing him.

But one candidate hasn't quit-- Ron Paul.

In an interview with CNN, Paul explained why.
 
"Well, it certainly isn't for the reason of disrupting a convention, as you are alluding to. That is not in my plan. That is against my plan. I don't like that even being a suggestion. I'm in it for very precise reasons - to maximize our efforts to get as many delegates as we can. I'm still a candidate and to promote something that is very, very important. That is a change in the direction for the Republican party to be a fiscal conservative Republican party.
 
Paul has 82 of the 1144 delegates
