Bob Barr’s Libertarian Party bid for the White House is the longest of long shots, but political experts say he may be able to exploit the unease some die-hard conservatives still feel about Sen. John McCain, the Republican nominee-in-waiting. Combined with the surge in turnout among Democrats during the primaries and a difficult political climate for Republicans, they see what could be a recipe for trouble for the GOP.

“Bob could be the Ralph Nader of 2008,” said Dan Schnur, a GOP consultant in California who worked on McCain’s 2000 campaign but is not involved in this year’s contest. Consumer advocate Nader is the third-party candidate many Democrats blame for helping George W. Bush narrowly win in 2000.

Barr also hopes to tap into the zealous grass-roots network of Rep. Ron Paul, who recently dropped his bid for the GOP presidential nomination and pledged to support “Libertarian-leaning Republicans.” Paul, a Texas Republican who ran for president on the Libertarian Party ticket in 1988, drew hefty campaign contributions online, but did not win any primaries.

With Barr in the race and if McCain loses to Obama, then Barr will be the reason.  He will be a convenient scapegoat for the loss.  That way the Repubs could save face for having a candidate that is thin on issues and can still keep a grasp on the money machine.
