Insofar as people/religion/ethnicities go..Bush was very much a "Liberal" in that he didn't have a racist bone in his body.
But he was conservative in every other way. War/oil/low taxes.
That's the economy conservatives like.
War is not a Conservative or Liberal Policy. It's just stupid. Oil? I don't recall which administration stopped oil imports unless you are pointing to Carter.
Low taxes is a Conservative plank in that it allows the citizen to spend his money rather than having a beaurocrat do it. However, a true Conservative also reduces spending to fall within collections.
Bush's spending outstripped collections so he was a Liberal in that way including the Drug aid given to seniors which was not paid for.
His social programs were Liberal. His spending was Liberal and he failed to stop the Sub prime lending which favored those of insufficient means and so was Liberal.
All of his actions were Liberal, but his party was Republican so the mind numbed robots of the left were told to oppose him, not his policies, and they did. The Left has a visceral hatred of Bush, but not so much of his policies.
Of course, the Big 0 has taken the imbalance of spending beyond any rational thought by a factor of 10 compared to the weak Liberalism of W.
By comparisson, W was a Conservative. By comparisson, live steam is cool compared to a blow torch flame.
