Sandra Day O'Connor (search) — the Supreme Court's key swing vote — announces her retirement and suddenly the law of the land on abortion, the death penalty, affirmative action and separation of church and state, is back in play.

Did Washington's long, hot summer just get longer and hotter? We'll discuss what comes next with Sens. Mitch McConnell, R-Ky.; Lindsey Graham, R-S.C., and Dianne Feinstein, D-Calif.

Plus, the confirmation battle to name O'Connor's replacement won't be waged in the Senate alone — outside interest groups want sway public opinion their way. We'll discuss the TV commercials, mass e-mails and campaign-style tactics with C. Boyden Gray, chairman of The Committee for Justice and former White House counsel, and Nan Aron, president of the Alliance for Justice.

And, we'll get powerful political punditry from Brit Hume, FOX News Washington managing editor, and our panel of FOX News contributors Mara Liasson and Juan Williams of National Public Radio, and Charles Krauthammer, syndicated columnist.
