I think Leno may have become a Bush convert. He recently had Bill Maher on the show and was arguing with him about Maher's leftist crapola. When Maher started attacking Bush, saying he was "devious" and dishonest, Leno defended him by telling how his wife Mavis, whose long-time cause was heading a group to help the women of Afghanistan, went to the White House for aid after the Taliban was kicked out. Leno said she's a lifelong Democrat from a big union family and didn't expect they'd even talk to her, so she was stunned when they ushered her into a meeting with Colin Powell and Condi Rice who asked, "What do you need?" He said she told them...And they not only promised to provide it, but then, they actually DID it! They kept their promise! If it had been the Clinton White House, they would've hit her up for a big contribution (or a BJ), made her some empty promises, and never followed through.
Ever since then, I've noticed that whenever there's some big news story involving Bush, like the State of the Union Address, Leno will do his usual "dumb Bush" jokes, but then he has Dennis Miller come on, knowing that Miller will support Bush and lambaste liberals. And unlike with Maher's appearances, Leno never argues with him, he just lets Miller rant while Leno sits behind the desk, laughs and feeds him straight lines. Miller has been on Leno's show about three times in the past six weeks, which is highly unusual booking procedure, unless there's an ulterior motive. I think it's Leno's way of supporting Bush without having to admit that he does.
