Thank you for your most interesting input.
Good point about Wallace. He certainly would be running, with LeMay as his running mate. They would have won the same states they won, regardless of who Nixon's running mate was.
I agree there would not be any significant difference in the election outcome. Nixon and Finch would win the electoral vote by a comfortable margin, as in the actual election, and with Finch instead of Agnew, I believe Nixon would have received a slightly larger share of the popular vote. Many voters were unsure enough about Agnew to vote for Humphrey.
Finch would not have created the skepticism and the derision that the Agnew candidacy generated, and Finch would have been taken more seriously as a credible Vice Presidential nominee than was Agnew.
With Finch as the running mate, there is a possibility that Texas and maybe Washington would have been won by Nixon.
Thoughts about this analysis?
Would Finch really have been more credible? I confess I know next to nothing about Robert Finch. Agnew was off-putting in a way Finch may not have been, but would people really feel that a two-year Lieutenant Governor was qualified to be a heartbeat away from the presidency?
