Good Monday morning. With a week to go before the Giants and the Pats meet in the Arizona desert, we -- and plenty of others -- still think the Super Bowl is the trophy a big winner could receive a few hours after polls close the following Tuesday. Consider the first four days of this week the pre-game show: No week has been more important to the presidential race than this one. Here's what Washington is watching today:

-- The Senate continues consideration of the FISA amendment bill, throwing the liberal netroots into another week of frenzy. For Democrats, the measure presents a problem and an opportunity: Ameliorate bloggers or homeland security-concerned voters. Both will be irritated by something the Senate does, presenting Republicans with what they see as a real opportunity. The House meets for morning business today, but no votes are expected before 5 p.m.

-- After the two chambers spend their days in session, Senators will slum it by heading to the House chamber, where President Bush will deliver his final State of the Union address at 9 p.m. Eastern time. The speech is sure to change the presidential debate, at least for a day, as Bush is said to be set to call for more bipartisanship, in the wake of the stimulus compromise, and urge action on FISA, making tax cuts permanent and approving trade deals with Peru and Colombia. It is unlikely he will offer any major new initiatives, according to White House press secretary Dana Perino, and don't expect any big Iraq announcements: General David Petraeus' next report to Congress doesn't happen until March.

-- While Bush's speech will surely inject some story lines into the campaign to replace him, this weekend was dominated by another subject: Barack Obama. Hillary Clinton's campaign had prepared the media for a 15-point loss. They might have been able to spin that into a wash. But Obama's stunning victory, in which he doubled up Clinton, propelled him to some huge headlines on Sunday, along with a rash of newspaper endorsements. He racked up massive margins among African Americans, who turned out in higher numbers than in any South Carolina primary in modern memory. That's exactly the message the Obama campaign needs to convey to rank-and-file Democrats worried about electability: He goes beyond attracting Independents and Republicans. He actually expands the Democratic base.

-- Just when Clinton was struggling to recover from the thumping, word of Senator Ted Kennedy's endorsement leaked. Kennedy and his niece, Caroline, will join Obama at what promises to be a mega-rally at American University here in Washington today. How convenient for cable news networks: They're sure to have satellite trucks, major reporters and live shots ready to go, giving Obama another huge day. The endorsement came despite a personal entreaty from Bill Clinton, the New York Times reports. After the Washington rally, Kennedy will join Obama on a western campaign swing and for events in the Northeast leading up to Super Tuesday.

-- It won't happen tonight during her response to President Bush's State of the Union, but Kansas Governor Kathleen Sebelius is set to offer Obama her backing as well, Marc Ambinder reports. Kansas is one of the states the Obama campaign thinks it can win on Super Tuesday, and he's going to spend Tuesday stumping across the state, including a visit to Eldorado, where his grandparents lived. Two big endorsements, both of which will have February 5 impacts, and a huge South Carolina win made this weekend all about Barack Obama. Such a weekend, for his campaign, could not have come at a better time.

-- John McCain's weekend was good for him in a more under-the-radar sort of way, but in a way that might well decide the Republican primary much before the Democratic race ends. In the last few days, McCain's won backing from the Fort Myers News-Press, the St. Petersburg Times, the Sun-Sentinel and a few other Florida papers, along with high-profile support from Senator Mel Martinez and Governor Charlie Crist. Mitt Romney had been seen surging in recent days, but backing from the state's two top Republicans might just be enough to turn it around for McCain. Then again, Romney's organization lost to Mike Huckabee's momentum in Iowa. Can McCain's organization overcome Romney's momentum in Florida?

-- The Democratic race has gone national, while the Republican race remains focused on Florida. If McCain pulls out a win, no matter the margin, he wins all of the state's 57 convention delegates, which would put him well in front of any of his rivals, both in actual delegate counts and in the battle for later states. McCain, in short, can all but close the deal in Florida. Romney, who in recent days has gone back to his Olympics metaphor and said he can survive a gold or a silver, will stick around, and has the money to do so, while Giuliani and Huckabee, who look set to trail by 15 or 20 points, could fade away.

-- One overlooked strategic blunder: Huckabee went straight from his Iowa win to New Hampshire, where he managed a respectable third place. Then he spent the next week in Michigan, where he again scored third. But the wheels had already started coming off before his narrow loss to McCain in South Carolina. There's value to competing everywhere, but once you win, you're allowed to choose your spots. Why didn't Huckabee spend more time in South Carolina instead of in Michigan and New Hampshire? Had that decision gone the other way, we might be singing a very different tune on his chances. And yet, Huckabee's only now beginning his forays into February 5 states, with a stop in Tennessee today. Shouldn't he just hunker down and spend the next several days in prominent Super Tuesday southern states?

-- Staged Media Event Of The Day: Twenty-two states will vote on February 5, giving editors a dilemma: Political pundits have all but concluded the Democratic race will not be over by close of polls on February 5, and the GOP race could be the same way. So, when will the nomination come to a conclusion? How about February 12, when three states hold their nominating contests? Editors will have a much easier time allocating coverage for those events: They happen to be in Maryland, Virginia and Washington, D.C., as the Post notes on its front page. This space will certainly offer dispatches from as many Metro lines as possible.

-- Today On The Trail: Obama rallies in Washington, while Clinton holds town halls in Hartford, Connecticut and Springfield, Massachusetts. Both will be in Washington for FISA votes and the State of the Union. Edwards will meet voters in Chattanooga and Nashville before heading to Springfield, Missouri. Giuliani has his last full day of Florida stumps, in Sanford, Clearwater, Fort Myers, Fort Lauderdale and Miami. McCain holds three events in Jacksonville before holding rallies in Orlando and Tampa, while Romney rallies in West Palm Beach, Fort Myers, Orlando, Panama City and Jacksonville. Huckabee rallies in Pensacola and raises money in Nashville, Tennessee before ending his day in Tampa. Ron Paul spends his day in Portland and Augusta, Maine.
