In every Presidential election held in my lifetime, the more charismatic or likeable candidate won the election. The only exceptions to that might be Johnson/Goldwater and Nixon/McGovern where neither of the candidates had much of an edge.
This year, it is again no contest in the likeability department. Senator Someone Else is a clear loser.
I was going on 15 at the time of Nixon/McGovern. I still remember the commercials citing that McGovern would cut the military by 1/3. Even with Viet Nam winding down, if I can still remember that, it is probably a safe bet to say that the majority of Americans thought that would not be a bright thing to do.
