Bob Barr records campaign message for Ernie Fletcher

Former Georgia Congressman Bob Barr has recorded a campaign phone message for Ernie Fletcher. In the message, Barr, a former Republican turned Libertarian, backs up Fletcher's claim that Anne Northup did not support voluntary prayer in schools while she was in Congress.

I don't understand why Bob Barr has recorded a campaign message for Kentucky's esteemed spineless governor. Maybe they were buds in Congress?
