I can't believe anyone hasn't thought of this before. It would be the ultimate reality show. We need single elimination debates for the Republican primaries.
Imagine a field of sixteen candidates fielding eight one-on-one debates. To decide the winner, Frank Luntz or Wolf Blitzer could moderate a republican focus group representing various party interests and they could decide who the winner was. Or just use overnight polling.
The remaining eight then would got the the round of four at which point they could all meet in the Final Four round all together.
The mind reels.
