I don't think he was. But there are those on this thread who are saying that Coulter was striking out at the Jersey Girls because she was defending Bush against them.
Coulter despises Bush, and uses him as she uses everything else in her life: as a prop for a book or column. She is entirely mercenary.
Coulter has supported the President since the Gore 2000 election hijacking and have frequently praised the President in subsequent columns.
She opposes some of his bone-headed policies, big deal. I'm sorry if she's not the 100% Bushbot that you and others are.
