How many debates do these guys need?
57, one for each state.
Lots of them.
More debates mean more exposure so that Joe 6-Pack and the rest of the sheeple might actually stumble upon some information about the candidates.
I've lost so much faith in the general American public that it wouldn't surprise if only 15% of the country has even watched more than one of these debates in it's entirety. The vast majority of the public consist of uninformed morons who get their information from the MSM. Many of these people won't even start thinking about the election until about 2 weeks before the General.
