Our exclusive guests this week:
• Gov. Ed Rendell, D-Pa., Obama supporter
• Rob Portman, McCain supporter and former director of the Office of Management and Budget

McCain and Obama race through another week of intense campaigning as the Supreme Court delivers two major opinions on the death penalty and gun control. Plus, the White House changes its stance on North Korea. We’ll talk about these issues and much more with key advisers from both campaigns: Pennsylvania Governor Ed Rendell, an Obama supporter, and McCain supporter, former Ohio congressman Rob Portman -- only on "FOX News Sunday."

Also, can a third party candidate affect the playing field in this year’s general election? We’ll ask the Libertarian Party presidential candidate Bob Barr.

Then, Barack Obama and Hillary Clinton make their first joint general election campaign appearance. Will the Democratic Party finally find unity? Joining us will be Brit Hume, FOX News Washington managing editor; Mara Liasson of National Public Radio; Bill Kristol of the Weekly Standard, and Juan Williams of National Public Radio.

Plus, our Power Player of the Week runs a talk show out of saloon. We’ll sit down with Carol Joynt, owner of Nathans Restaurant and host of "The Q& A Cafe."
