Good Tuesday morning, and happy Election Day. We've been waiting for this for two solid years, and we're going to have some fun with it. Tune in tonight for our analysis and live results on XM Radio's POTUS '08, which you can listen to here for free. We'll be on from the time the first polls close at 6 p.m. ET to the time the last results are known. Here's what Washington is watching today:

-- The first results are in, and Barack Obama has a serious lead, with 32 votes to John McCain's 16 in Dixville Notch and Hart's Location, New Hampshire. The two tiny towns in the north country really don't serve as indicators; instead, the tradition of voting right after midnight is just another of the symbolic moments of the day. Obama's win in Dixville Notch, the New Hampshire Union Leader points out, is the first time a Democrat has won the town since 1968, when Hubert Humphrey beat Richard Nixon there by an eight to four margin.

-- As voters across the country head to the polls, they are considering two key differences between the candidates, Gallup's Frank Newport writes. Obama stands for change, and the vast majority of voters who are looking for a change are going to pick the Illinois senator. McCain is the safer, more experienced pick, and his voters overwhelmingly cite experience when they give their reasons for choosing him. If McCain goes down tonight, watch for ample criticism that he didn't play up his experience enough. Sure, the strategy didn't work for Hillary Clinton in the primaries, but for a much older, more conservative electorate in the general election, it might have made a difference.

-- Meanwhile, the traffic on the way to Obama's final rally just outside Washington was horrific, we're told. But for those denizens of the District who hadn't seen the Democrat before got a special treat, as the candidate reached back to the primaries for his old "Fired up! Ready to go!" bit, per The Swamp's John McCormick. As McCain drew smaller crowds in the final days of the campaign, Obama ended his campaign with a rally for 90,000 in Manassas, Virginia, telling the crowd they have to go vote even if it rains.

-- That's a concern for both campaigns, especially in eastern North Carolina and Virginia, where a coastal storm is expected to dump rain and wind on voters heading to the polls. Voters in the Pacific Northwest will have to contend with rain and, in some higher elevations inland, snow, which might hurt Republican turnout, though in Washington and Idaho, two states that aren't expected to be close either way. But it's going to be a beautiful, warmer than average day around the Midwest, a perfect time to stand outside in four-hour lines with your closest friends. Keep updated on the day's weather with the Weather Channel's election coverage.

-- McCain, never willing to throw in the towel, is eschewing his normal movie-going tradition on Election Day to head to Grand Junction, Colorado, a Republican area where he is hoping to gin up turnout. McCain will stop by Albuquerque, New Mexico for a last-minute rally before returning home to Phoenix.

-- Just in time for absolutely no one to hear about it, McCain running mate Sarah Palin has been exonerated of wrongdoing in the so-called Troopergate scandal, the Anchorage Daily News' Lisa Demer writes. An independent investigator hired by the state Personnel Board sharply disagreed with a special counsel representing the state legislature, saying the counsel used the wrong state law under which to base his conclusions. The only thing the Personnel Board investigator found fault with was the use of personal email accounts, which are less secure than official email accounts.

-- Finally, even if he wins it will be a bittersweet day for Barack Obama. Madelyn Dunham, the woman who helped raise Obama in Hawaii and served as what he called his "rock" passed away in the early morning hours Monday, the campaign announced late yesterday. Obama saw Dunham a week and a half ago, leaving the campaign trail to say goodbye. Obama learned of her passing early yesterday. Win or lose, it would have been nice for Obama's grandmother to be able to see Election Day take place.

-- Predictions Of The Day: After more than a year running Politics Nation and almost two years covering the campaign trail, it's time to finally lay down our predictions. Tragically, someone's already done that for us: Turns out our projected map looks exactly the same as Karl Rove's, which Marc Ambinder posts, giving Obama 338 electoral votes and the White House for at least four years. So we'll have to stick with the House and Senate predictions. Democrats will net no fewer than eleven seats in the House and no more than 47 seats, though our prediction is a net gain of 26 seats (30 Democratic wins, while four of the party's incumbents lose). Republicans will lose a net of eight seats in the Senate. Are we right? Or are we crazy? Check in tomorrow to find out.

-- Today On The Trail: Obama will hit polling places in Indianapolis to talk with voters before heading back to Chicago for a game of basketball. Tonight, he holds his election night celebration at Grant Park in Chicago. McCain will vote in Phoenix this morning before rallying in Grand Junction and Albuquerque. McCain's big party tonight is at the Biltmore Hotel in Phoenix. The last polls in the country will close at 1 a.m Eastern. Thanks for joining us during this incredible run; now, go vote.
