What SNenc says is true. I really wish there was some balance to the board.
However, as a conservative/libertarian type poster, I’ll give the benefit of the doubt and answer the OP in good faith.
My list of issues with Bush:
his policy choices
Campaign Finance Reform. He shouldn’t have signed this unconstitutional legislation. Congress and the SCOTUS are both equally to blame, of course, but Bush’s refusal to veto this bill was pure cowardice. IHMO, he didn’t want to take the political heat for an issue that most voters don’t care that much about, even though he knew it was the right thing to do.
Not cutting the size of government more. Bush is trying cut the budgets of 7 of the 16 Cabinet positions, but any money saved is going to the homeland security department and defense budget. He should be cutting everything across the board.
Generally not following up on campaign promises and talk from his speeches. I hear Bush talk about letting younger workers invest portions of social security. I hear Bush talk about vouchers for schools. I hear Bush talk about these things and don’t see much action. We have a Republican controlled House and Senate with a Republican president. These two things should be getting done. He has been talking about them since election.
his personality
Well, I don’t really know the guy. 
I guess his public speaking ability could be called “personality”. Sure, he could be a better speaker, but it doesn’t bother me that he isn’t.
I do wish he were a bit quicker on his feet at a press conference. As president, that is a part of his job and he could be better at it. But, he is improving IMO. Improvements here would also help to ensure that he beats Kerry come November.
his past history
I’m not going to base my vote for him on any past history before he was president, unless something very outrageous was to surface. He is the president now, and I approve of the job he is doing. That is what I will look at, not how well he ran a baseball team years ago.
It’s fishy how his service with the national guard ended. However, it’s still a plus to me that he served in the military and was a fighter pilot. It doesn’t bother me that he got out of going to Vietnam because if I were his age I would have also.
his personal character
His religious beliefs do bother me somewhat. As an atheist, I would love to see a non-religious president. But, that just is not going to happen. Things have been relatively stable on this front. After three years of office abortions aren’t any closer to being illegal, despite Gore’s warnings to the contrary. Faith based initiatives I don’t like. Teaching creationism in school is just plain stupid.
I could probably come up with more if I kept at it. I still agree with Bush a lot more than I disagree with him. I plan on voting for him.
