Our exclusive guests this week:
• Sen. John Thune, R-S.D., McCain supporter
• Sen. Claire McCaskill, D-Mo., Obama supporter
• Karl Rove, former senior adviser to President Bush

Sen. Barack Obama wraps up his overseas trip to the Middle East and Europe. Will this be remembered as "the moment" when Obama shook off the label of inexperience and became presidential? Or will voters question why a presidential candidate chose to spend his time in foreign lands instead of addressing issues here at home?

Meanwhile, Sen. John McCain spent his week hammering Obama's assessment of the situations in Iraq and Afghanistan. Was McCain effective at driving home a consistent message and at the same time steering some of the news coverage back his way? We'll ask key supporters of both: Sen. John Thune, a McCain supporter, and Sen. Claire McCaskill, an Obama supporter — only on "FOX News Sunday."

Then, the state of the race: We'll get the latest on the battle for electoral votes and analysis of where the candidates stand in critical swing states from the architect of two general election victories, Karl Rove.

And, the "veepstakes" continue. With the conventions looming, just how close are the candidates to picking their running mates? Joining us will be Brit Hume, FOX News Washington managing editor; Mara Liasson of National Public Radio, Bill Kristol of the Weekly Standard, and Nina Easton of Fortune Magazine.

Plus, we'll take a look back at a classic Power Player who's still asking for Ferris Bueller: economist Ben Stein.

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