"FAILURE DOESN'T RALLY THE BASE....The conventional wisdom at this point insists that Bush and the congressional GOP are touting the anti-gay constitutional amendment to rally the base. Grassroots activists are frustrated about Republicans' disregard for the religious right agenda, excessive spending, inaction on immigration, etc., and, while everyone knows the amendment isn't going to pass, a vote is supposed to make the activist base feel better."

Kinda makes you wonder?? could be they are going to cover up a big failure "Iraq" with a smaller failure "kill all the gays", but I don't know. Ask me they have something up their sleeves and this is the smokescreen. I would keep one eye open.
