And then there were two!

With Ron Paul, the tea party favorite and congressman from Texas, all but dropping out of the Republican race for the presidential nomination, that leaves just former governor Mitt Romney to carry his party's banner into the fall campaign against President Barack Obama.

Interestingly, though, Paul urged his legion of ardent supporters to continue their fight at the state party level and cause as many problems as possible for Romney.

"Moving forward, however, we will no longer spend resources campaigning in primaries in states that have not yet voted," Paul said in his statement. "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."

It seems very unlikely Paul will endorse Romney as the party's nominee since the two strongly have been at odds during debates over foreign policy, government efforts to fight terrorism at home, spending and other Libertarian-type issues, which all exactly the issues that have drawn him a loyal grassroots base.

Paul may be the last of the GOP contenders to fail to endorse Romney.

A longtime member of the U.S. House of Representatives, Paul is not running for another term this fall.

It will be interesting to see if the Libertarians and Paul supporters vote for Romney in the fall or will they continue their fight to sway his positions on Libertarian philosophies
