Why not just include all 16 candidates and expand the debate to 4 hours, with only a 5 minute break each hour for commercials in between ?
That would mean slightly more than 10 minutes talking time for each candidate.
Because nobody besides us, and probably not most of us, would watch a four hour debate. Plus, candidates would probably have to use the bathroom. Some of the older ones probably wouldn't be able to stand for four hours anyway.
A) Yes, that's a fair point.
B) They can go to the bathroom during the 5-10 minute commercial breaks each hour.
C) Is there a requirement that the candidates need to stand ? What about a sitting debate ?
