(CNN) – With the last of Mitt Romney's former presidential rivals now backing the likely presidential nominee, there is one candidate who hasn't quit the race – and doesn't foresee lending his support to Romney any time soon.
Texas Rep. Ron Paul said in an interview on CNN Wednesday that he is staying in the race to impact the party's agenda and to reconcile his differences with Romney would, at this point, be "pretty hard."

"It certainly isn't for the reason of disrupting the convention," Paul said of his continued candidacy. "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."
His slate of 82 delegates is a far cry from Romney's 904, some 240 away from the magic number of 1144 needed to clinch the GOP nomination. Rick Santorum and Newt Gingrich, who each quit their own candidacies in recent weeks, collected more delegates than has Paul.
Paul said leveraging his collection of delegates won't simply to land a primetime speaking role "just to give a speech for the sake of giving a speech."
That "doesn't have much appeal to me, but I think moving an agenda is very important," Paul said.
The budget and foreign proposals he's heard from other candidates aren't satisfying, he said, although he did not offer specific changes policies which would cause him to warm to Romney's candidacy.
Paul suggested he was not concerned that his continued candidacy could hurt Romney's campaign against President Barack Obama in November.
"Well of course there's always a possibility I can beat Mitt - I mean, I can beat Obama, too," he said. "I think that I could beat him, and every Republican that's run would have a pretty good chance of beating the president."
