Here's another one in our occasional posts about political odd couples: Turns out actor Vince Vaughn also likes GOP presidential hopeful Ron Paul.

Vaughn, star of comedy films such as The Wedding Crashers and The Break-Up, is scheduled to introduce the Texas congressman tonight at the Liberty Political Action Conference in Reno.

"Ron and Vince are friends," says Jesse Benton, Paul's campaign chairman.

Vaughn hosted Paul and his wife, Carol, at the 2009 premiere of his movie, Couples Retreat, and endorsed Paul's book, End the Fed, as a "must read" for all Americans.

Paul, who is making his third presidential bid, is a longtime critic of the Federal Reserve Board and has been pushing for an audit of the central bank.

The president and the maverick are running almost dead even in a hypothetical 2012 election matchup.

Texas Republican Congressman Ron Paul earns 38% of the vote to President Obama’s 39% in the latest Rasmussen Reports national telephone survey of Likely U.S. Voters. Fourteen percent (14%) like some other candidate, and eight percent (8%) remain undecided. (To see survey question wording, click here.)

Just a month ago, Obama posted a 41% to 37% lead over Paul, who ran second to Minnesota Congresswoman Michele Bachmann in the recent high-profile Ames Straw Poll in Iowa.

Paul, whose long run afoul of the GOP establishment with his libertarian policy prescriptions, picks up 61% of the Republican vote, while 78% of Democrats fall in behind the president. Voters not affiliated with either of the major political parties prefer the longtime congressman by 10 points – 43% to 33%.

But Paul still has a long haul among voters in his own party. He ran fourth last week in Rasmussen Reports’ most recent survey of Likely Republican Primary Voters with nine percent (9%) support. Texas Governor Rick Perry, the new face in the race for the 2012 Republican presidential nomination, has jumped to a double-digit lead over Mitt Romney and Bachmann with the other announced candidates trailing even further behind.

In that same survey, 43% of likely primary voters expressed a favorable opinion of Paul, while slightly more (45%) registered an unfavorable view of him. This included 15% with a Very Favorable regard for Paul, who ran unsuccessfully for the party’s presidential nomination in 2008, and 14% with a Very Unfavorable one.

Still, Paul, popular with many in the Tea Party movement, runs better against the incumbent than another Tea Party favorite, former Alaska Governor Sarah Palin.Obama leads Palin 50% to 33% among all likely voters, making her the only potential GOP candidate to date against whom the president’s support has risen out of the 40s.
