From the Washington Post:
ATLANTA — A fiery former GOP congressman who gained national prominence for doggedly pursuing impeachment of President Clinton has some Republicans worried he’ll play spoiler in a tight presidential contest.
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.
