Yes, Ron Paul was still running for the 2012 GOP nomination. And yes, Ron Paul is still running for the 2012 GOP nomination - he's just announced that he's going to stop spending money on his campaign, which is basically his way of saying that he's going to stop running without actually saying it. Mind games.
In an email sent to his supporters today, Paul attempted to clarify his decision:
Moving forward, however, we will no longer spend resources campaigning in primaries in states that have not yet voted. Doing so with any hope of success would take many tens of millions of dollars we simply do not have. I encourage all supporters of liberty to make sure you get to the polls and make your voices heard, particularly in the local, state and congressional elections, where so many defenders of freedom are fighting and need your support.
We say "attempted," because he didn't succeed in clarifying anything there, except that now we really only have Mitt Romney left to make fun of in this race.
