George Phillies wrote an extensive piece on the candidates Barr had supported (Republicans all) against whom the LP was running candidates. http://www.rationalreview.com/content/46361

Briefly these are LP Senate candidate in Georgia Allen Buckley whose opponent, Saxby Chambliss received $3,500 from Barr's PAC.

LP Senate candidate in NH Ken Blevens whose opponent John Sununu received $3K from Barr's PAC.

LP Senate candidate in Virginia, Bill Redpath (!) whose opponent Gilmore received $1K from Barr's PAC. Hey, Bill Redpath, that's a big thank you from Bob Barr for all yer help.

LP Congress candidate Thomas Hill in North Carolina opposing Robin Hayes who got $1K from Barr's PAC. Tom Hill and other LP members in NC had to fight there way onto the ballot with tens of thousands of signatures this year. Isn't it ironic that Barr benefits from the LP NC efforts to put him on the ballot and repays LP NC candidate Hill this way?

Texas LP Congress candidate Ken Ashby. His opponent Jeb Hensarling received $3,500 from Bob Barr's PAC.

And in Idaho, the LP is running Kent Marmon for Senate. As you noted, Larry Craig has received lots of financial and encouragement from Barr.

I'm kinda sick of it. I've been working with Tom Knapp on the Boston Tea Party since the LP platform was eviscerated in 2006.
