Everyone wants to be your friend when you’re chairman of the Senate Rules Committee. Just ask Don Balfour. The Snellville Republican’s campaign fund has collected nearly $85,000 since Jan. 1, for a total of $683,000 since January 2006. No one’s even run against him in that period. The Rules Committee places bills on the Legislature’s calendar, unless it chooses not to — which means the Senate will never, ever vote on your bill. That’s why Don has so many friends.
