It will be interesting to see what Gilmore and Hunter have to say in their short answers that might cause the top three to fumble with a counterpoint. This debate really needs to be 4 hours long and/or less questions asked so everyone has more time to respond.
They should have fewer questions asked, and also narrow the list of topics for each debate. There's just way too much ground to cover, and the candidates only have time to give thumbnail answers on each topic. Have a debate on Iraq, a debate on foreign policy issues besides Iraq, a debate on entitlements, a debate on immigration, etc. That would give you some time for some decent back and forth.
