John McCain will be the Republican Party's presidential candidate in November. Most Republicans certainly know who John McCain is, but there still seems to be a question as to just what he is. President Bush said last week that there was "no doubt in my mind he is a true conservative." But is he a Ronald Reagan conservative, or more like a Bob Dole moderate? Or is he like Dwight Eisenhower, who claimed in the 1952 nomination battle that he was "just as conservative" as his opponent, Sen. Robert Taft?
