Today, on the Ed Morrissey Show (3 pm ET), we have a great show lined up for you! In the first half, Andrew Malcolm joins us for our weekly conversation, in which we’ll talk about Obama’s big sell of Sotomayor on Capitol Hill, Government Motors and Obama’s promise to stay out of its operations, the two politically-driven murders and varying reactions to them, and more.

In the second half, we’ll talk to Florida’s Speaker of the House and candidate for US Senate Marco Rubio. We’ll ask him about running against an endorsement from a national Republican group in a primary, why he thinks he best represents Florida, and what his policy priorities would be if elected. Don’t miss this conversation with the man at the center of the GOP firestorm! And give big thanks to Val Prieto at Babalublog, who arranged it for me!

Now you can join the conversation in the chat room! Be sure to register at Ustream to participate in our raucous live-chat sessions. (And if the log-in prompt doesn’t come up in the chat box below, use this link instead.) Jazz Shaw of The Moderate Voice moderates the chat, and he has his Troll Gun Trivia Contest running before the show, for those who get there early — and are registered!
