Good morning and happy Halloween. After a long night watching debates (yeah, like anyone actually watched) here's what Washington is keeping an eye on today:

-- The Senate considers version two of the SCHIP bill, with a vote on cloture coming this evening. The White House has already promised a veto. The House tackles trade adjustment assistance and the Hardrock Mining and Reclamation Act. The House Administration Committee's Elections Subcommittee holds a hearing on the use of robocalls in federal campaigns, and the House Ways and Means Committee takes up a bill to ensure free trade between the U.S. and Peru.

-- Much coverage today on the question of whether Hillary Clinton was tripped up late in last night's debate when asked about New York Gov. Eliot Spitzer's move to give driver's licenses to illegal immigrants. One journalist point out to Politics Nation that a two-hour debate can trip a candidate up, and Clinton's non-answer-double-answer looked to many like a major slip-up. But the big question for Barack Obama and John Edwards: Was it a slip-up that they can exploit, or do they have to make the argument that Republicans will be able to exploit it? (By the way, my round-up of the debate here.)

-- Speaking of which, here's something to watch: Spitzer caused Clinton trouble last night, as did powerful Ways and Means chairman Charlie Rangel, whose massive tax overhaul Clinton was asked if she would support. The tax plan, the New York Times writes, is a big target, as is Spitzer's plan. Clinton mentioned her work as First Lady of Arkansas last night. Could that be a theme that becomes more prominent once the general election gets started? After all, it's a pseudo-red state to New York's big, bright baby blue.

-- After the fracas in Philly, one thing is clear: The nastiest general election campaign would be a contest featuring ... Rudy Giuliani and Joe Biden? After Biden's biting one-liner on Rudy's sentence structure ("A noun, a verb and 9/11"), the Giuliani campaign came out with a release on their differences: "Rudy rarely reads prepared speeches and when he does he isn't prone to ripping off the text from others." Back shot Biden's team: "It's pretty obvious that they can't defend themselves on the real charge that Mr. Giuliani walked away from the cops and firefighters who were waiting for the 9/11 Commission to be enacted and the Biden crime bill to be restored." Makes all the attacks on Clinton look downright civilized.

-- More marking of calendars: We saw fireworks in the debates last night, but the fur will really fly when Republicans and Democrats meet at Des Moines Register-sponsored debates, rescheduled from January for 12/12 and 12/13 respectively.

-- Back in Washington, President Bush addresses an issue today that the GOP, for its long-term well-being, needs to fix. Bush will talk to grocery store owners and food manufacturers about health care, and what he sees as Democrats' slow walk toward socialized, government-run health care. While Democrats are trying to expand Medicare and other government-run programs, Bush wants to boost private insurance markets, he will argue. Democrats have long led on credibility surrounding health care, according to polls. Whether the argument can be won by touting the business merits of one's plan, rather than the health merits, is a question Congressional Republicans hope are resolved by the president today.

-- Keep an eye on this: The first attack mailings are out in South Carolina, and nowhere can one find the words "Romney" or "Mormon." Instead, the mailers, from Sen. John McCain, take after Clinton and fellow Republican Rudy Giuliani. McCain, the mailer claims, "is a stronger candidate than Rudy Giuliani in the general election" and wonders about Hizzoner's record on choice, per CNN's Peter Hamby. The mailer is an invitation to a town hall meeting in Myrtle Beach, with an appropriately small universe of targeted homes, but the shot at Giuliani makes one wonder whether the Mayor will be a bigger target than Romney. The latest RCP South Carolina Average has Giuliani leading by just 0.2 percentage points over Fred Thompson.

-- Nod Of The Day: John Edwards got a pre-debate boost when members of the New Hampshire Service Employees union announced they would back his campaing, despite heavy lobbying from Clinton and Obama. SEIU couldn't come up with a national endorsement, so they freed their state chapters to do what they wanted. Edwards now owns nods from New Hampshire and Iowa, which means other state chapters can't send volunteers in to help their candidates of choice. Labor prizes left to win: AFSCME, which is said to be on the verge of endorsing Clinton, the National Education Association and the Communications Workers of America, per the NYT.

-- Today On The Trail: John Edwards is in Peterborough and Manchester, New Hampshire, and takes his kids trick-or-treating in Bedford. Barack Obama is trick-or-treating with his kids at home in Chicago. Mitt Romney's kids are probably too old to trick-or-treat, but he's in Adel, Iowa, for a house party. Rudy Giuliani visits a restaurant in Nashua, while John McCain presents his health care platform to a Kaiser Family Foundation-sponsored forum in Washington. Fred Thompson holds a press conference in San Francisco.
