Let’s see...liberated over 50 million people from dictatorships, pushed for a renaissance of private ownership in the US, defended at every opportunity each individuals right to life, attempted to give private ownership to part of social security, espoused the belief that liberty was a right given to each individual (on the planet) from God. Yes, I can see where you think President Bush was not conservative...
He ran on "no nation building" and not being the world's police men, which are conservative Constitutionalist ideas. But he invaded Iraq for no reason and sought to be the world's police (just as Clinton and his dad had done) to the point that we, as a nation, are almost bankrupt.
In addition to his failed world police vision, he tried amnesty for law breaking illegals, saw the biggest expansion ever of federal governmental power, and presided over the largest budgets in U.S. history (until Obama broke his records). Bush is the reason the Tea Party was born; we were tired of not having any advocate for the Constitution as the Republican party had lost its way.
