Actually you don’t want to give a guy the second slot, that you don’t ever want to be president. The V. P. is generally the shoe-in when an eight year term comes to an end.
I wouldn’t be in favor of Newt nominating Romney as his running mate.
Gingrich/Palin?.......You betcha!
Nope. It's not. Has only happened 3 times in history. Washington's VP Adams, Jackson's VP Van Buren, and Reagan's VP Bush. By the way, all three previous VPs only served one term.
