Senators dominate this weekend’s Sunday shows, where they’ll discuss the next steps for health care reform and Afghanistan’s Nov. 7 presidential run-off election, with both candidates there making appearances.

CBS’s “Face the Nation” interviews Sens. John McCain (R-Ariz.) and Russ Feingold (D-Wis.).

ABC’s “This Week” hosts Senate Minority Leader Mitch McConnell (R-Ky.) and Sen. Claire McCaskill (D-Mo.).

NBC’s “Meet the Press” features Senate Finance Committee members Sens. John Cornyn (R-Texas) and Chuck Schumer (D-N.Y.).

“Fox News Sunday” has a foreign-policy heavy line up with Abdullah Abdullah, the challenger for president in Afghanistan, Sens. Carl Levin (D-Mich.), chairman of the Senate Armed Services Committee, and Jon Kyl (R-Ariz.).

Additionally, Fox host Chris Wallace interviews Bruce Josten, the chief lobbyist for the U.S. Chamber of Commerce, which has been targeted by the White House for its opposition to financial regulatory reform and climate change legislation.

CNN’s “State of the Union” also hosts Abdullah, along with Sens. Orrin Hatch (R-Utah), Ben Nelson (D-Neb.), Jim Webb (D-Va) and Sherrod Brown (D-Ohio).

CNN’s Sunday afternoon show “Fareed Zakaria GPS” interviews Abdullah’s opponent in the Afghan election, President Hamid Karzai.

The lone Republican to vote for a health care bill, Sen. Olympia Snowe of Maine, appears on Bloomberg’s “Political Capital,” where she’s standing firm in her opposition to a government-run health care plan, according to advance transcripts.

“A public option at the forefront really does put the government in a disproportionate position with respect to the industry,” Snowe said in the pre-taped interview.

Finally, “Washington Watch” features Sen. Roland Burris (D-Ill.), Rep. Yvette Clarke (D-N.Y.) and actor and musician Ludacris.
