Here's our list of five organizations to follow tonight:
AARP, the behemoth group that doesn't back one presidential candidate over the other, will be tweeting not from just one, but two, Twitter accounts (they are that big, people). Keep an eye on @AARPadvocates for live-tweeting action on AARP-related issues (cough, Medicare, cough). And @AARP will carry post-debate reactions.
With jobs likely to dominate tonight's debate, the National Association of Manufacturers will have plenty to say. Watch them fire up their @ShopfloorNAM Twitter machine.
You know who else cares about the economy, jobs and government regulations? The National Federation of Independent Business, which will be live-tweeting from @NFIBLive with a snazzy hashtag, #Big4SmallBiz. Catchy!
The AFL-CIO is live-blogging tonight's event, but follow @AFLCIO for 140-character snippets of what labor is saying. (Our prediction: Obama=good, Romney=bad. Just a guess.)
The American Coalition for Clean Coal Electricity will be keeping an eye on energy issues and will be quick to jump anything they deem inaccurate. Follow them on @AmericasPower.
