(CNN) — Former Republican Rep. Bob Barr is now the Libertarian Party's presidential nominee — and a potential headache for John McCain, as he reaches out to conservative voters who might otherwise vote for the GOP nominee in November.
The former Georgia congressman — who left the Republican Party two years ago, citing differences over fiscal policy and concerns over civil liberties — was nominated on the sixth ballot at the party’s convention in Denver. The vote on the sixth ballot was 324 for Barr, and 276 for Mary Ruwart, the last remaining candidate out of 14 originally seeking the Libertarian nomination.
