Bob Barr: Libertarian candidate for president and a former GOP congressman could steal votes from John McCain, some in party fear.
Bob Barr's Libertarian Party bid for the White House is the longest of long shots, but political experts say he might be able to exploit the unease some die-hard conservatives feel about Sen. John McCain. 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 Mr. McCain's 2000 campaign but is not involved in this year's contest. Consumer advocate Mr. Nader is the third-party candidate many Democrats blame for helping President Bush narrowly win in 2000.
Rep. John Linder, a Republican who defeated Mr. Barr in 2002 after Georgia's Democratic-controlled Legislature redrew congressional boundaries to put the two lawmakers in the same district, said he didn't think Mr. Barr would top 4 percent of the vote.
"But in some states that may be enough," Mr. Linder said.
Democrats seem gleeful at the prospect. Tad Devine, a Democratic strategist, said Republicans "are crazy if they aren't worried about Barr."
"Undoubtedly any votes he gets come out of McCain's votes," Mr. Devine said.
Mr. Barr, a former federal prosecutor, was swept into Congress with more than 70 other House GOP freshmen in 1994. An articulate, sometimes outspoken orator, he gained attention as the first lawmaker to call for Mr. Clinton's resignation over the Monica Lewinsky scandal, and he was one of the House prosecutors who pressed the impeachment case in the Senate.
Mr. Barr also was known during his four terms in the House for his opposition to softening drug laws and his support for gun rights.
Some Republicans aren't worried about Mr. Barr's candidacy.
"No reasonable conservative is going to vote for anyone except McCain," said former House Speaker Newt Gingrich.
Georgia and its 15 electoral votes have been expected to go Republican on election night, and McCain spokesman Jeffrey Sadosky said he remained confident they still would.
