Keep sipping the koolaid...
DeLay quite because it was time to get out of Dodge City...
Ron Earle has his problems but so did/does DeLay...
Delay quit because even if he had been found innocent of all charges, the damage had been done to his reputation and he was certain to lose his Majority Leader post and maybe even re-election. His relatively weak showing in the primary proved it. Once you are Majority Leader, it's hard to go back to being a regular congressman.
So he quit so he could start the 1 year wait before he can legally become a lobbyist.
