Bob Barr, Libertarian, Could Hurt McCain And Help Obama

Ross Perot's third-party candidacy in 1992 helped Bill Clinton win his first term against Pres. George H. W. Bush, and Libertarian Bob Barr could also drain enough votes from John McCain to enable Barack Obama to win in November.

And Obama would need that help if Ralph Nader gets in again.

Yeah, I know it's early to make these predictions, so just call them observations.
