@jcboy,
I will always wonder how much the Eagleton situation lowered McGovern's vote pulling. After the information on Thomas Eagleton's mental health was leaked and he was replaced with Shriver, it likely lowered confidence in McGovern. That's unfortunate since (in my view at least), McGovern was what the country needed and he would have put us on a better track than the Nixon admin. sent us down.
Of course it's seen by most that McGovern would have lost anyway; however, perhaps the defeat would not have been as harsh.
Rest peacefully George McGovern.
