President Obama holds a news conference tonight at 8 pm ET, his latest effort to sell his health-care plan to a public that, if you believe some polls, is growing more dubious.

And it will be the main topic in today's Political Junkie segment on NPR's Talk of the Nation.

Plus: A week's delay in the Senate Judiciary Committee vote on Sonia Sotomayor, Sarah Palin's final week as governor (let the Sean Parnell era begin!), the F-22 defeat is a victory for Obama, and Robert Byrd returns to the Senate.

Join host Neal Conan and me every Wednesday at 2 p.m. ET for the Junkie segment on TOTN, where you can often, but not always, find interesting conversation, useless trivia questions and sparkling jokes. And you can win a Political Junkie T-shirt!

Last week's program — featuring Nevada political analyst Jon Ralston — can be heard here.

If your local NPR station doesn't carry TOTN, you can hear the program on the Web or on HD Radio. And if you are a subscriber to XM/Sirius radio, you can find the show there as well (siriusly).
