SOMEWHERE BETWEEN CLAREMONT AND LEBANON, N.H. — The final day before New Hampshire's first-in-the-nation primary. Sen. Barack Obama is playing it safe, taking no questions from voters at his first event.

He took questions once yesterday among his several campaign stops.

This morning Obama told a few hundred that he feels great, "but I've been talking a lot."

He said he'd met with a doctor and asked what they would prescribe. The remedy? "Shut up," Obama said, chuckling.

Later on the press bus, the campaign clarified the medical situation.

Obama spokesman Ben LaBolt said a local doctor visited his boss sometime before 11 last night in the hotel as a "precaution" to check on the senator's voice, which as been strained since the last night he was in Iowa.

"The doctor concluded there was no infection and told him that the best thing he could do was to rest his voice for a couple of days," he said.

Obama reminded the crowd in Claremont — which had few undecided voters — to make sure to vote tomorrow.

"Do not take this race for granted," he said. "I know we had a nice boost over the last few days, but elections are funny things. You have to actually wait for votes to be counted. … We have not won anything yet."

Some attending the Claremont event had come from nearby Vermont, which holds its primary March 4.

Several polls have Obama with a large lead over Clinton, who has a packed campaign schedule today and has been doing tons of local press interviews.

I have a story up this morning from a day on the campaign trail with Sen. Hillary Clinton. Her supporters were very excited yesterday and canvass volunteers said they knocked on more than 10,000 doors over the past few days on her behalf.
