All Obama, all the time

If you're watching TV Sunday morning or late Monday night, it'll be rather difficult to avoid President Obama.

CBS announced today that Obama will be the sole guest Monday on the "Late Show with David Letterman."

"President Obama's appearance will mark the first by a sitting US president on the 'Late Show' and his first visit back to the show since his election. In total, this will be President Obama's sixth visit to the broadcast -- he last appeared on the 'Late Show' September 10, 2008 during the height of his 2008 presidential election campaign," the announcement said.

Also, CNN announced that Obama will be interviewed on its "State of the Union" show on Sunday. He will also appear on Univision.

That follows word Monday that Obama will appear Sunday on "This Week" on ABC, "Meet the Press" on NBC, and "Face the Nation" on CBS.

At this point, Obama is skipping Fox News Channel, which a study released Monday found had been very critical in its coverage, and the Fox broadcast network, which has recently refused to preempt primetime programming to air Obama's speeches. MSNBC does not have a Sunday news interview show.

All the face time on television comes as Obama puts the hard-sell on for his health care overhaul plan, whose fate in Congress could be decided in the next few weeks.
