Will Ron Paul be Mitt Romney’s last rival standing? We ask that question because if you sort through the Nevada caucus results, look at this week’s GOP events, add in a few financial disclosure forms, and shake, you can produce a scenario where Representative Paul outlasts Newt Gingrich and Rick Santorum. That would make the Texas libertarian the only non-Romney to run all the way to the Tampa Republican convention in August.

Yes, we know Paul actually placed third in Nevada’s Saturday vote. He’d hoped to do better, placement-wise. He ended up with 19 percent of the vote. Ex-Speaker Gingrich got 21 percent. Mr. Romney reached the 50 percent threshold.
