Vice-President Goldwater under LBJ would’ve been a hoot. Vice-President McGovern under Nixon, not so much (though after a year a half of him as President with Nixon’s impeachment, he probably would’ve lost in ‘76 — although returned to VP).
Vice-President McGovern under Nixon would have been the ONLY way to “restore our Republic”. No doubt since the original 1787 wording of the U.S. Constitution provided for that and we mustn’t EVER tamper with what the framers came up with. ;-)
Some other fun ones:
Vice President Charles Evans Hughes in Wilson’s 2nd term, when he suffers a massive stroke.
Vice President William Jennings Bryan in a McKinley administration. He would have taken oath in 1901 and veered this country on the path to socialism, 12 years BEFORE the “progressive era” the anti-17thers are screaming about.
Vice President Horace Greeley in a Grant administration
Vice President John C. Breckinridge in an Lincoln administration (talk about a Civil War!)
Vice President Winfield Scott in a Pierce administration
Also, if the 12th was repealed: we have gotten a President Winfield Scott Hancock in 1881, a President Thomas Dewey in 1945, and a President Nixon in 1963.
