HuffPost reporter Sam Stein joined guest host Chris Hayes and New York Times opinion columnist Ross Douthat for the "Rapid Fire" segment of Monday night's "Ed Show." The panel laughed over Mike Huckabee's Sunday touting of his poll numbers among Republicans, which Douthat termed characteristically "charmingly passive-aggressive." Next, they discussed the Supreme Court's repudiation of Chicago's laws on gun control, an issue which Stein ruefully said Democrats -- including President Obama -- have basically ignored. Finally, Hayes moved on to a recent poll suggesting that one-quarter of Americans don't believe Obama was born in the United States.
