I don’t have a fast connection (only about 700 kbps) and https://www.c-span.org works fine.
There are other good sources. NBC has Game 7 of the NLCS and ESPN has Monday night Footbal.
I’m in Thailand. C-span was perfect the last debate. Youtube is frequently unwatchable it breaks up so much, so that is saying something.
If, in practice, the cspan video stream doesn’t work, you should be able to hear audio on WMAL.

(You have the advantage of being able to listen to Mark Levin before the debate, to boot!)
Watch the live thread here, it will be more analytical than FOX, and spare the pain of having to listen to the officious punk try to shuck and jive around Romney, and watch his vapid juvenile facial and body gestures... and be embarrassed that got 50 million votes in 2008
