Liveblogging caucus night with Yahoo News, ABC and Tucker Carlson

At long last, some people--not very many, but some--are casting actual votes in the campaign for the 2012 presidential nomination of the Republican Party. As Iowans vote and as the results come in, you can read and contribute to the liveblog below, featuring real-time discussion and analysis from Yahoo News and ABC News journalists, including: Jonathan Karl, a senior political correspondent for ABC News; Rick Klein, the senior Washington editor for ABC News' "World News with Diane Sawyer"; and Chris Suellentrop, the deputy editor for blogs at Yahoo News. Also participating will be Tucker Carlson, the editor of the Daily Caller. The live blog also features tweets from Yahoo News and ABC News reporters who are on the ground in Iowa.
