A reminder of the rules of the game. We want you to select your favorite pundit, however you determine that. Do they make you laugh? Do you agree with them most? Would you want them over for dinner?

We chose our Sweet 16 pundits based largely on the number of times they've appeared on the Sunday news shows in 2014 -- the pinnacle of punditry.
