Here's our blow-by-blow recap of the debate from last night's live-blog.
And here's Perry Bacon Jr.'s analysis of what we learned from the showdown.
And here are the big moments you might have missed.
Other than the GOP debate, there were some goings-on for Democrats too. NBC's Monica Alba wraps Hillary Clinton's appearance on Jimmy Fallon.
And here’s the AP’s report on Biden’s visits to Michigan and Ohio today.
How it played:
The AP: "Trump underwhelms, Fiorina shines in GOP debate"
The Washington Post headline: "Jousting with Trump signals new stage in race"
The New York Times: "Candidates Use Second G.O.P. Debate to Taunt Donald Trump"
The Des Moines Register: "Iowans see gains for Fiorina, Christie in GOP debate"
The New Hampshire Union Leader: "Trump spars with Bush, Fiorina, at contentious Republican debate"
The Miami Herald: "Republican rivals try to bruise Donald Trump, but debate delivers no knockouts"
The Cleveland Plain-Dealer: "John Kasich remains above the fray but under the radar in second Republican presidential debate"
The Milwaukee Journal-Sentinel: Scott Walker struggles to be heard at debate, with 3 questions, little airtime
The Wall Street Journal writes: "Substance Made a Comeback in Second GOP Debate." MORE: "While many of the questions posed by the CNN moderators began with a recitation of comments Mr. Trump has made, which left him still at the center of the conversation, his competitors managed to launch a conversation that, for the first time in weeks, got beyond the Trump orbit."
CHRISTIE: Here's our wrap of his big moment taking aim at Fiorina and Trump for their "childish back-and-forth."
FIORINA: She said during the Wednesday night debate that women 'heard very clearly' what Donald Trump said about her appearance.
TRUMP: He started off the debate by slamming Rand Paul, writes NBC's Andrew Rafferty.
