In N.H., Tactics Shift On The Ground And Over Airwaves

Republican candidates who want their spot on the ballot for the New Hampshire primary have just two more days before hitting the filing deadline. Mitt Romney submitted his papers Monday.

"We've got great volunteers from all over the state," Romney said as he filed, "and they're going to come together and turn out the vote on primary day, and of course obviously I hope to do real well here in New Hampshire."

So far, he has. The latest polls in New Hampshire give Romney a double-digit lead over all other contenders. But in the frenetic rise and fall of presidential primary politics anything can change between now and January, especially with the battle for the state's airwaves beginning to heat up.
