The only one left is Fox and I am surprised at Fox. Well Fox Cable will have it so that's good.
I think it is kind of silly for Fox or NBC to broadcast any speeches, as they have 24 hour news channels. Anyone who wants to see it can see it on ABC,CBS or one of the cable stations. Anyone who doesn't want to see it can go to any of the other 50+ stations on cable. Anyone who doesn't have basic cable by now needs to be checked for a pulse.
Well, Fox network is not Fox cable, and they have always been reluctant to run things like this, but gradually have begun covering things more and more since 2000 or so.
They usually just stick on the FNC feed, though sometimes they actually have a separate broadcast.
It sounds like they are going to run it now if the other posts are correct.
