How about Geraldine Ferraro?
Geraldine Ferraro probably didn’t help Mondale because Reagan was so popular, no running-mate could have helped Mondale win. Mondale probably would have received more votes if his running-mate was someone who had more political experience and higher name recogntion. Before the 1984 election, the last five democrat vice presidents had been U.S. senators. They were Mondale, Humphrey, Johnson, Barkley, and Truman. If Mondale’s running mate was Edmund Muskie, who was a senator from Maine and secretary of state; or Pat Moynihan, who was an ambassador to the UN and senator from New York; Mondale probably would have received more votes than he did, although Reagan still would have won.
