Our exclusive guests this week:

• Tom Daschle, co-chair of the Obama campaign, former Senate Majority Leader, D-S.D.
• Tom Ridge, McCain supporter, former governor of Pennsylvania

Both campaigns give us a preview of things to come as we race towards November. Senators McCain and Obama attacked and accused one another of flip-flopping on key issues including offshore drilling, public financing of the election and the War on Terror. We'll tackle these tough topics and more with two key supporters — both contenders in the veepstakes — former Senate Majority Leader Tom Daschle, co-chair of the Obama campaign, and Tom Ridge, former governor of Pennsylvania and McCain supporter, only on "FOX News Sunday."

Then, Obama says no to public campaign financing. How will McCain compete against Obama's high-powered fund-raising? 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 helps keep the Earth “cool.” We’ll sit down with Kathleen Rogers, president of the Earth Day Network.

So check your local listings and we’ll see you on the next "FOX News Sunday."
