I certainly agree he's cut some taxes but it's worth remembering he came out against the expanded sales tax (Florida's really big tax) only when a poll showed the public thought it a terrible idea, something like 80-20. He could have killed it before it got any momentum as he said he would based on his experience as Secretary of Commerce in Martinez' administration fifteen years ago. He made a very conscious decision not to.
In the first two years of his term annual spending rose in excess of 7.5%, his third year he pushed for and got a change in accounting which makes comparisons difficult but which, if you believe the numbers, resulted in a third year decline in state spending! Last time I checked, the Department of Banking and Finance still couldn't make an adjusted year to year comparison. My guess is the number, if adjusted, still increased by over 7.5%. Evidently the possibility spending might be reduced never enters his mind. Last Friday, for example, the papers reported the state took over $1 billion in trust fund money, which will have to be replaced, to pay day to day expenses.
If Compassionate Conservatism is Rockefeller Republicanism under a new name then I suppose you're right, by your definition he is a conservative. To those of us who believe in smaller government, however, it's clear he's not what we know as a conservative.
