The Republicans might do a bit better in 1974.
Oh, god, Percy? Look, he lost fair and square to Frank Church. Just because he won the popular vote doesn't make him President.
He didn't win the popular vote. I don't know why so many conspiracy theories of Church committing fraud exist. He ran against corruption in government, for goodness sakes. And he won a landslide.
I think Church may not run in 1976. He may not be pushed to do so. The result is that an ideology different than his pragmatic progressivism becomes the ideology that defines America.
