A lot of people supported Bush and the neocons at the time, but most see them for what they really are these days.
Nothing wrong with learning from your missteps. I certainly have. The difference is us conservatives have the humility to acknowledge we are not perfect and actually learn as situations change while not abandoning our principles. Because of this we become better people. On the other hand, liberals don’t seem to learn and stubbornly cling to an ideology that is proven to be counterproductive and fails in the long run. Because of this they all seem to grow more and more bitter and angry as they get older.
