I don't like him because I believe there was a chance to reform the tax code and switch our system sales tax rather than income tax. He did nothing to push this forward at all. Plus, he spends like a drunken sailor. He isn't a fiscal conservative.
I like the fact that he is not swayed by opinion polls. While he may be dead wrong, he undoubtedly has more information than any of us could possibly possess. The down side to this is that he has trouble recognizing when his ideas don't work and doesn't change when it is required.
Overall, I view his presidency as a negative, but not as much as some on this board.
