To even mention Allen with the likes of leaders like Goldwater or Reagan is nonsensical.
There is no "there" there.
Allen would be another Dole.
Goldwater was, in a way, somewhat like McGovern. Each was the instrument by which a faction gained power in its party. Reagan was the charismatic figure who, in 1980, led the faction to victory. Goldwater's function was to voice the complaints of those who were disappointed with Dewey-Eisenhower-Nixon Republicanism. Had Nixon won in 1962, however, Goldwater would never have got his shot, and of course, if Nixon had not screwed up as President, Reagan would never have got his. Looking back, we have to thank Richard Nixon for his blunders.
