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.

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.
