Manchester, New Hampshire (CNN) - The largest newspaper in the nation's first primary state has a message for presidential candidate Mitt Romney: "New Hampshire is watching."
The New Hampshire Union Leader published an editorial Tuesday chiding Romney for continuing to campaign in Nevada while several of his GOP opponents boycott events in that state.
Nevada's GOP moved up the date of its caucus to Jan. 14, which threatens New Hampshire's long-held first primary status and may push its nominating contest into December. The state's election law states that it not only goes first but also seven days before any similar contest.
Led by former Utah Gov. Jon Huntsman, many in the GOP field are pledging to skip Nevada's contest if the state continues to threaten New Hampshire's status.
A national committeeman on the Nevada GOP's executive board last week alleged Romney had a direct role in pushing up Nevada's caucus in order to gain more momentum for his campaign.
On Tuesday, the editorial board argued such a move by Romney would be against New Hampshire's best interest.
"Romney is willing to sacrifice an institution beneficial to the republic (the New Hampshire primary) for his own political advantage," the editorial asserts. "The Nevada move weakens all 2012 candidates not named Romney and threatens all future New Hampshire primaries."
Romney's campaign responded last week but didn't directly address allegations that he interfered with the primary calendar process.
"Governor Romney respects the essential role our Primary plays in selecting our Republican nominee, and is unequivocally committed to New Hampshire hosting the first Primary contest during the 2012 cycle and beyond," Romney's New Hampshire adviser Jim Merrill said in a statement last week, adding that the governor will compete in all nominating contests, as New Hampshire retains its first-in-the-nation primary status.
Meanwhile, Romney continues to show his strength in Nevada. On the same day as the CNN/Republican Western Leadership Conference in Las Vegas, Romney announced the support of 35 state representatives.
He also opened his Nevada campaign headquarters Monday night.
The Union Leader explains New Hampshire is beneficial to candidates who lack huge campaign chests and who spend time meeting voters through retail politicking in the sate.
"Romney's campaign bank balance is stronger than his skills at retail politics," the editorial states.
The editorial board warns other states could be "emboldened" by Nevada in the next presidential cycle in 2016, further threatening New Hampshire's status.
Romney has a significant lead in the recent state polls, but voters here are still largely undecided.
The secretary of state has not set a date for New Hampshire's primary but has suggested it could be held in early or mid-December.
