Sunday news show guests to preview impending Afghanistan decision

The Sunday morning shows this weekend will buzz with anticipation about President Barack Obama's Afghanistan speech on Tuesday.

CNN's "State of the Union" will interview three key lawmakers as a preview to Obama's address. Sen. Richard Lugar (R-Ind.), ranking member of the Foreign Relations Committee, Sen. Jack Reed (D-R.I.), a member of the Armed Services Committee, and Rep. David Obey (D-Wis.), chairman of the House Appropriations Committee, will sound off on the future of U.S. policy in Afghanistan.

CBS's "Face The Nation" will feature Senate Armed Services Committee chairman Carl Levin (D-Mich.), who will play a central role in approving funds for a possible troop escalation.

Both Levin and Obey have floated the idea of a war tax to finance any surge. Expect their respective interviewers to press them on that topic.

Following Levin on CBS will be Dick Armey and NY-23 candidate Dede Scozzafava, who will likely sound off on the future of the Republican Party.

On "This Week," ABC's George Stephanopoulos will preview the Afghanistan decision with Sens. Bernie Sanders (I-Vt.) and Lindsey Graham (R-S.C.). Sanders's take may be indicative of what Obama can expect from the left flank of his own party.

"Fox News Sunday" will speak to Sens. Jon Kyl (R-Ariz.) and Evan Bayh (D-Ind.) about Afghanistan. Republicans have suggested they will support Obama if he calls for more troops. Look to see just how supportive Kyl and Graham are, and whether they take the opportunity to criticize the president for delaying his decision.

Fox will also sit down with Howard Dean and Mike Huckabee, who will discuss both Afghanistan and the future of their two parties heading into 2010 and 2012.

Meanwhile, "Meet the Press" will take a break from the news cycle to host a "giving back" discussion with megapastor Rick Warren and Bill and Melinda Gates.
