It’s not hypocritical, it’s earned. Bush and Palin are genuinely stupid, genuinely evil, and especially in the case of Bush have caused immense harm. They deserve nothing but hatred and contempt, earned by their personalities and actions. That’s not the same as sneering at someone just because they are poor or sick or homosexual or female. The Republicans condemn and mock people for things are are outright lies; we have a recent example of Limbaugh doing just that, mocking a woman who lost an ovary as a “slut”.
