While it may be true that Goldwater bridged a certain gap that existed in the conservative movement of the mid-1960`s, he ended his life supporting homosexuality, opposing right to life of the unborn child and defending Bill Clinton. Not a legacy that conservatives should be proud of.
Goldwater may have projected conservatism for a short period, but it was Ronald Reagan who actually promoted and advanced conservatism to new levels. Barry Goldwater took the worse beating by a GOP presidential candidate in the 20th century. Reagan produced two landslide political victories in 1980 and 1984. Reagan also gave American's real tax reform, a victory over communism in the Cold War and revitalized the US economy and military armed forces.
OTOH, in all reality, Goldwater didn't do jacks**t for America.
To be fair, AU-H2O married a liberal late in life, when he was slipping into senility. She unfairly bent his ear.
