You never specified when the POD was. If we put the POD 20+ years ago, it could make nearly anyone president. Maybe have Ron Paul not run for President as a Libertarian in 1988. If he runs for the Senate or Governorship, or tried to return to the House earlier than OTL, maybe he would be seen as more of a mainstream Republican, instead of an outsider. From there his career could go almost anywhere. Who know? By 2008, he might be a legitimate front-runner for the Republican nomination.
If you want a more recent POD, we'd have to go for something crazy, like having all of the other candidates drop dead.
