I suppose politicians have always wanted to get re-elected, but there's a kind of a feeling now that if you just discredit your opposition, it makes it easier for you to win. I don't think that's necessarily true.
I firmly believed throughout 1971 that the major hurdle to winning the presidency was winning the Democratic nomination. I believed that any reasonable Democrat would defeat President Nixon. I now think that no one could have defeated him in 1972.
If Reagan wins, I'd sell the farm and buy a bomb shelter.
