On this day in 1998 the House approved two articles of impeachment against Bill Clinton. In more inspiring events, on this day in 1777 George Washington led his battered Continental Army into winter quarters at Valley Forge (and you think it's cold right now). Now for today's top election stories:

"After Delay, Clinton Embarks on a Likability Tour" (Patrick Healy, New York Times) With husband Bill by her side, Hillary Clinton took flight yesterday in the campaign helicopter to tour Iowa on what reporter Healy describes as her "warm-and-fuzzy" tour. As his presence indicates, a big part of the tour is Mr. Clinton himself, who -- with the help of Magic Johnson -- can still work the crowds.

"Clinton Secret Weapon: Organization" (Jackie Calmes, Wall Street Journal) A profile of Clinton's Iowa organizer Teresa Vilmain, nicknamed the "hummingbird on acid," who's in charge of making sure that if Clinton comes up short in Iowa, it won't be because of the campaign's poor ground game.

"Iowa Poll Spotlights Importance Of Turnout" (Dan Balz and Jon Cohen, Washington Post) Speaking of organization, a new Washington Post/ABC News poll finds silver linings for the top three Democratic candidates: More than seven out of ten Obama supporters say they will definitely participate in the caucuses (compared to 59% for Clinton supporters); seventy percent of Clinton supporters, however, say they will definitely caucus for her, with 59% saying they are very enthusiastic about her compared to 49% for Obama. Two-thirds of Edwards supporters, meanwhile, have caucused before, while more than half of Clinton and Obama supporters never have.

"Huckabee Now a Candidate With Something to Lose" (Mark Leibovich, New York Times) In an interview conducted while the candidate ran on a hotel treadmill, Mike Huckabee talks about the perils of going from also-ran to frontrunner. "I have a lot more enemies right now, but that's part of the deal," said a sweating Huckabee.

"McCain Embraces Tax Cut Turnaround" (Stephen Dinan, Washington Times) One of conservatives' biggest beefs with John McCain was his opposition to the the Bush 2001 tax cuts. Now the senator says, if president, he would make most of those tax cuts permanent as part of his economic package, which includes elimination of the alternative minimum tax.

"Giuliani Faces 9/11 Backlash" (Stephen Braun, Los Angeles Times) A group of firefighters who lost family members on September 11 are organizing a tax-exempt committee to go after Rudy Giuliani's leadership and decisions on that day.

"Obama: Look beyond Iraq" (Dan Gearino, Quad-City Times) More than ending the war in Iraq, Obama said the next president must also end the "mind-set" that led the nation to war. Speaking to a Des Moines crowd, Obama's comments were just the latest in the ongoing feud between him and Clinton over who has the best foreign-policy experience.

"For Republicans, an Early Start That Might Lead to a Late Finish" (Sam Youngman, The Hill) Reporter Youngman sizes up the GOP race with short analyses of the dynamics in each early state. The lesson of course is that it's still anyone's nomination.

"Population churn adds uncertainty to races" (Sarah Liebowitz, Concord Monitor) In New Hampshire, potential new voters make up more than 23% of the primary electorate pool. The demographic shift has made gauging voter opinion and potential turnout difficult to nail down.
