Our exclusive guests this week:

• Sen. Dianne Feinstein, D-Calif.
• Sen. Dick Durbin, D-Ill.
• Karl Rove, former White House senior adviser

Just days away from Super Tuesday II both Senators Clinton and Obama fighting it out for the 444 Democratic delegates up for grabs.

Does Senator Clinton need a win in both Ohio and Texas to keep her candidacy alive? Does Senator Obama have the numbers on his side to win the nomination?

We'll ask Clinton supporter Sen. Dianne Feinstein and Obama supporter Sen. Dick Durbin only on "FOX News Sunday."

Then, a look at the general election campaign. How do Obama and Clinton match-up against John McCain? We'll talk strategy with former White House senior adviser and FOX News contributor Karl Rove.

And, does Hillary Clinton risk hurting Democrats if she stays in the race without big wins on Tuesday? We'll discuss with our Power Panel: Brit Hume, Washington managing editor of FOX News; Bill Kristol of The Weekly Standard, and Mara Liasson and Juan Williams of National Public Radio.

Plus, our weekly look, at the ups and downs, "On the Trail."

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