If you didn't like Nixon Reagan and Bush presumably you liked McGovern, Carter, and Dukakis better. Or did you support a fringe candidate who had no chance of ever winning thereby making it easy for you to condemn the rest of the world?
Leftists do not belong in the Republican party.
Leftist like Nixon, Reagan, and Bush?
Actually, Nixon was leftist in many things. Remember his wage and price control schemes? Doesn't get much more left than that. Bush 41 was a miserable president, and was a liberal fuddy duddy who fumbled the Reagan legacy and helped to usher in the Clintoon debacle.
Nixon was a big-government liberal who gave us fine conservative policies such as racial preferences and abortion on demand. Reagan was a genuine conservative who made a mistake by bowing to liberals in his own party and appointing O'Connor (who didn't seem so horrible at the time, to be fair). and King George "Read my Lips" I yet another elitist big government liberal. His "conservatism" included raising taxes, kowtowing to the Chinese, yet more racial preferences in addition the moronic David Souter. His appointment of Clarence Thomas, generally a defender of the constitution, was one of the few bright spots in an otherwise Carteresque administration.
Two out of three of the presidents mentioned are clearly liberals. McGovern, Carter and Dukakis are leftists - as are Chaffee, Snowe, and Collins (to name merely three). McCain is nothing more than a mouthpiece for George Soros - bought and paid for. As I say, leftists (and corruptocrats like McCain) need to be removed from the Republican party. The sad truth is that leftists probably control something like 70 percent of the wealth in the country, so they generally get their way.
