About last night: The Republicans running for president met in Sioux City, Iowa, last night for their last scheduled debate before the Iowa Caucuses on Jan. 3. And while they largely kept their attacks on President Obama, Newt Gingrich found himself on the receiving end of several tough questions from rivals about his record.
Is Ron Paul on the rise in Iowa? And could Paul - or someone else - mount a third party general election campaign? We'll get into those questions tonight.
Plus, we'll remember Christopher Hitchens. The brilliant writer and frequent Hardball guest died last night.
