Granny Annie's promise to veto any Concealed Carry bill that reached her desk, and GW's promise to sign the same bill is what cost her her job. Once she proved that she was proud that she didn't trust the people who hired her, she was on her way out.
Why "cut the old lady a break" to someone that evil? Waco was under her watch, and she never had a problem with it.
She also lost in 1994 when she ran a relentlessly negative campaign- calling GWB Shrub, saying that he "lost his little Herbert", etc.- and Bush ran on the issues. People were turned off by her nastiness. She thought it was cute.
I will never forget Grannie at an elementary school and a kid asked her why she was so mean to George Bush all the time. She laughed and said, "Aw, sonny, you just gotta learn that's what politics is all about." All her entourage laughed too, and Bush refused to respond to the incident. He won. She lost, and apparently continues to lose.
