"Because you expected him to do liberal things, and he turned out to be a conservative?"
Conservative? LOL! I expected him to be conservative but the guy is a moderate. You have no idea what a conservative is.
At that time he had over 90% of Republican support, and deservedly so, because he had stood strong for America in the war on terror (which he is still doing), and he had cut our taxes and made multiple pro-life, pro-morality decisions that were very conservative, as well as rejecting Kyoto and the World Court.
As to whether or not he is a conservative down the line, the answer to that is an obvious no. But if you made the decision not to vote Republican ever again after two years, you should have never voted for a Republican before, because he was being as Conservative a President as we had ever had.
And to tell the truth, with the change in the judiciary due to his leadership and conservatism, this country will move more notably to the right because of Bush than it did because of Reagan.
