Good Thursday morning. Politics Nation is back in Washington just as things seem to be blowing up. At this point, there is nothing that can happen in the 2008 primary season that will surprise us. Here's what Washington is watching this morning:

-- The Senate picks up its work on reforms to the Consumer Product Safety Commission, but the most important work continues in the Budget Committee, where battles over the Fiscal Year 2009 budget are just beginning. In the House, a bill to reauthorize AmeriCorps will get a vote today, while the House Appropriations Committee will hear from Deputy Secretary of State John Negroponte on a new supplemental budget request for Iraq and Afghanistan. President Bush today has the honor of meeting a World War I veteran before speaking at Constitution Hall on the fifth anniversary of the Department of Homeland Security.

-- A day after Hillary Clinton won a reprieve with victories in Texas, Ohio and Rhode Island, the focus shifted to Pennsylvania and that state's April 22 primaries. But forget Pennsylvania: Both campaigns and the national media are focusing, once again, on Michigan and Florida, where top politicos are beginning to discuss the possibility of a revote. Should those two contests be scheduled and executed before the June 10 deadline, they would add another 128 and 185 elected delegates respectively, along with 29 super-delegates from Michigan and 25 from Florida, becoming bigger combined prizes than the 158 pledged delegates Pennsylvania offers.

-- But it's not as simple as setting a date, and the wrong people are being blamed for the confusion. While DNC chief Howard Dean has taken heat for purportedly failing to force the two campaigns into a compromise, the race is really not Dean's to inject himself into. In fact, Dean is unable, per party rules, to make certain rules flexible. "What we can't do is change the rules in the middle of the campaign. Both candidates knew what the rules were," Dean said on MSNBC this morning, part of a media blitz in response to the criticism.

-- The onus falls on local actors in Michigan and Florida, which would have to find the money -- probably close to a combined $20 million -- to run the primaries, and would also have to establish plans that allow voters in their states to actually cast ballots, including military service members. Getting ballots to Iraq, Afghanistan and other U.S. outposts around the world takes a long time, effectively meaning that, even if Floridians and Michiganders were to vote on June 10, their ballots would have to start going out as early as late April. A month and a half is not a long time to plan an election in which 5 million-plus people would vote.

-- Michigan Governor Jennifer Granholm, a Democrat, and Florida's Charlie Crist, a Republican, issued a joint statement yesterday calling for their delegates to be seated and offering their support for some sort of re-vote, Marc Ambinder writes. Dean's own statement thanked both governors for their willingness to help, but it's up to the states to decide, not the national party. The two states' congressional delegations sat down last night to discuss potential scenarios, MSNBC reported.

-- Not to say Pennsylvania won't be important. At the moment, the Keystone State is getting the lion's share of the attention from both camps, earlier contests in Wyoming and Mississippi notwithstanding. Pennsylvania will be "Iowa on steroids," state Democratic Party chairman T.J. Rooney likes to say. Both candidates, after Mississippi's April 11 primary, will have a full six weeks to focus on one battleground. Both will have no choice but to contest the state, and a resounding defeat for one or the other could be the breach in the dam that helps super delegates finally make up their minds, en masse.

-- As for actual candidates, Hillary Clinton may be riding a wave in recent days, but here's an ominous sign: The netroots may be turning against her. Back in July, we penned a look at how Clinton, never a hugely popular figure among lefty bloggers, had done her best not to win friends, but to neutralize potential enemies. Andrew Sullivan writes the new animosity, led by DailyKos, is coming as backlash from some of Clinton's new negative ads -- which Kos suggests makes rival Barack Obama look more black. This column has always been skeptical of the power the netroots claim over the Democratic Party, but they're certainly not enemies anyone can afford. Just ask Joe Lieberman.

-- Meanwhile, all is not well in HillaryLand. After more than two months of voting, the campaign has not wrapped up the nomination, something that was supposed to happen by Iowa, or New Hampshire at the latest. Chief strategist Mark Penn is getting the most blame, all from inside the campaign, where employees began denying Penn credit in Tuesday's wins before they even happened, the Post's Peter Baker and Anne Kornblut write. Still, at least some of the blame falls on the candidate herself. One of her favorite books, Baker and Kornblut write, is "Team of Rivals," about the squabbling within Abraham Lincoln's cabinet. Hoping for the same sense of competition, Clinton built her team with knowledge of their own disagreements. Clinton, one source tells the pair, won "despite us, not because of us."

-- Over in ObamaCountry, Tuesday's primaries may have slammed the breaks on a number of super delegates who were set to publicly announce their support for the senator. Had Obama split the day, or had he won more primaries than Clinton, a swarm of new super delegates could have increased pressure on Clinton to get out of the race. Some reports indicated up to 50 new super delegates would have headed Obama's way -- a claim backed up by Obama backer and Missouri Rep. Lacy Clay, per Political Wire. Yesterday, though, Obama pulled in just two new backers. But if the tide is really reversed, when will the Clinton camp start rolling out their own delegates?

-- Reversal Of The Day: It's all about super delegates, and the number supporting one candidate will make clear the Democratic Party's winner. On the other hand, the other candidate's recipe for success relies on stopping supers from backing the rival. A month ago, it was Clinton looking to collect the big-name delegates and Obama looking to stop her inherent advantage. Today, it's Obama on the collecting side and Clinton defending. One of Clinton's keys to victory, The Fix writes, is her ability to halt Obama's progress among elected officials and party leaders. In politics, a week really is a lifetime.

-- Today On The Trail: John McCain (remember him?) meets voters in West Palm Beach before chatting up the media. Later today, he holds a fundraiser in Atlanta. Clinton has a press conference set for 3:30 p.m. in Washington before heading down to Mississippi to address the state's Jefferson-Jackson-Hamer Day dinner. Husband Bill Clinton is hosting three events in Wyoming. Obama holds town hall meetings in Casper and Laramie, Wyoming, hoping to capitalize on the next opportunity to win a state. Wyoming will award twelve delegates through Saturday caucuses.
