Vice President Bob Barr

Just saw this article over at Reason talking about Bob Barr as a potential Libertarian Party candidate. This could be trouble for the GOP as a credible LP candidate could cost a few percentage points in several states. That could easily be the margin of difference in places like Florida.
But what if McCain asked Barr to be his running mate? This could kill several birds with a single stone. Barr has impeccable conservative credentials, probably moreso than McCain. He would help energize the small government wing of the right back to the GOP. After eight years of Bush, that would be a much needed thing.
Most of the focus on possible VP picks have centered on finding a minority candidate to counter either Obama or Clinton. This is extremely short sighted and would clearly be seen as an affirmative action pick rather than a best possible person. Sarah Palin and Bobby Jindal are both rising stars but they need more time and experience before they take the national stage. 2012 or 2016 probably, but not quite yet.
