I have an hypothesis: The reason President Bush's approval ratings are slipping is because he is too liberal. How so, you ask? Look at what he's done through the lense of the left.
One, he spends money like a liberal, perhaps moreso, and is out of step with his conservative ilk who typically cut spending for social programs. Two, he's in a war with an agenda that he has failed to make clear, plus he remains in a combat situation that has no pull-out strategy, much like Clinton with Bosnia, Haiti, or Samalia. Three, he "lies" to the American public about all sorts of things, just like Clinton did during his scandals. Four, he subjects our national interests by appealing to the UN, just like Clinton. Five, he makes the same marketing appeal to us with his form of Christianity, just like Clinton did when, during the photo ops, he would swing his huge bible on the way to church. Six, he makes these scripted "town-hall" type gatherings with the troops, just like Clinton did with his "town-hall" gatherings around the country. The left knows this as political opportunism; they hate it in Bush, but applaud it with Clinton.
The fact is we know Bill Clinton IS a sleazeball, so his actions fit his person. He couldn't be labeled a despicable hypocrite; we expect him to play the part of the pondscum that he is. So Clinton could pull it off and absorb the attack against liberalism with his weak, immoral character. Bush, on the other hand, can't pull it off. He is awkward trying to act "Clintonesque;" his character can't absorb the liberalism and the people actually see the hypocrisy and brown-nosing. We want the tough, conservative Bush that we elected, not some pandering "new-tone" wimp who is trying to make everyone on the Beltway happy. Nothing irritates people more when you have a sycophantic leader trying to get people to like him. Bush is trying to do this, and the polls show it. In Bush, liberalism is as appealing as a naked Bella Abzug, and the left is blushing with embarrassment. They know a weak ideology when they create one.
