I would expect C-SPAN to rerun this debate several times over the next few days...the positive buzz this receives should bring in quite a few new viewers.
not to mention, C-SPAN has it at its archives, available like your home recorder. I see only 47 “likes” to face book and only 6 tweets. Those who do facebook and tweet should give the ‘debate’ some positive comment to raise its vibibility.
