How about switching them around after their second term, just to make sure everything stays on the same Republic Road. Like Cruz-Palin, Cruz-Palin, Palin-Paul, Palin-Paul, Paul-Nugent, Paul-Nugent, Nugent-West, Nugent-West, etc. =)
I like the way you think.
Gotta leave room for a Gowdy or a Chaffetz in there too. Just in case we need spares. ;-)
