that and he killed a woman and tried to cover it up

He did run for president as a candidate in 1980 against the incumbent Carter in the primaries but was unsuccessful.

And, as it turned out, no sniper could take him out cuz he was bobbing and weaving in a drunken stupor most of the time - well, when he wasn't drowning women in his car.
