Republican Debate Tonight on TV: What Channel?

Tonight on TV, there's going to be a Republican debate about the next presidential elections. I want to know which channel is going to broadcast the complete debate.
I know there have been many Republican debates on TV so far, and I personally support Ron Paul, but I can't remember the channel or the network of tonight's event.
I seriously think it's going to be difficult for Republicans to have a victory against Obama, their only chance is if our current President messes up.
Do you know the TV channel and can you confirm it's actually tonight?

The GOP will hold its Republican and Tea Party debate tonight and you'll be able to watch it on TV, specifically on ABC and its news channel.
This time, the Republican debate is going to be sponsored by ABC News, Yahoo!, and local TV WMUR. The Republican debate tonight will be held at Saint Anselm College in Manchester, New Hampshire. I believe other channels will be there too.
I won't miss it tonight, I still think some of the guys have a chance. Besides, there's nothing else on TV I'd rather be watching.
