New Hampshire's first-in-the-nation presidential primary is getting short shrift this year. Rick Perry is pretending it doesn't exist. Other candidates are splitting their time between demandingly hands-on New Hampshirites and the next primary state, South Carolina. Even the Granite State's promised-to-be-fiery weekend debates largely fizzled. "In this race, New Hampshire is serving as off-Broadway for South Carolina," says Byron York at the Washington Examiner. This year's primary is so "devoid of energy," adds Walter Shapiro at The New Republic, that New Hampshire should change its motto to "Live Free or Die of Boredom." But New Hampshire still has plenty of excitement, and Tuesday's voting is critical, just as it is in every presidential cycle. Here, three reasons to pay attention:

1. Romney is set to make history

Part of the reason for the lack of drama is that everybody expects Mitt Romney to win. But that's newsworthy in itself, says Ron Fournier at National Journal. Assuming he does win, Romney would be the first (non-incumbent) Republican presidential aspirant to sweep both Iowa and New Hampshire since Iowa cut to the front of the line in 1972. "The GOP voting coalitions in Iowa and New Hampshire couldn't be more different," and if Romney wins both, "he can accurately claim to be the most viable GOP candidate." Besides, New Hampshire is the first state with real delegates at stake, "and that's what this is all about": Winning the most delegates.

2. Who comes in second place matters — a lot

There may be "little apparent drama over which candidate will win," says Paul Steinhauser at CNN. But there's a "high-stakes race for second," and even third place, and the momentum such a strong showing could give a candidate like Jon Huntsman. Remember, the list of New Hampshire runners-up who went on to win the nomination is long and illustrious, says John Toole in the North Andover, Mass., Eagle-Tribune: Eugene McCarthy; George McGovern in 1972; Walter Mondale in 1984; and "Comeback Kid" Bill Clinton in 1992.

3. And anything can still happen

New Hampshire allows its undeclared or decline-to-state voters to cast ballots in whichever primary they want to, and the large number of independents in the Granite State makes the vote "unpredictable and fascinating to watch," says Carla Marinucci in the San Francisco Chronicle. "There is no more perfect example of why New Hampshire matters than the 2008 Democratic primary," says Noah Rothman at PoliticOlogy. Hillary Clinton beat a surging Barack Obama, despite trailing in the final polls by as much as 13 points. It "was so shocking that few could even believe the exit polls." The lesson for the GOP candidates is that even with hours to go, "anything can happen, and in the era of the 24-hour news cycle, there is still time to change minds in this race."
