The former Massachusetts governor went on to decry Obama's proposed tax increases on millionaires and billionaires as potentially stymieing business owners who filed taxes on behalf of their companies.

"This is an administration where I don't know what they've been thinking about, they certainly haven't been talking to small businesses," Romney said.

The Republican candidate's remarks were notably abbreviated relative to past stump speeches, but it was clear Romney was more interested in doing crowd work among the small gathering. The former governor now owns a home in New Hampshire and campaigned heavily there before its first-in-the-nation primary, giving the event more a sense of a casual homecoming than campaign event. At multiple times during his remarks, Romney stopped to salute individuals in the crowd.

Ayotte argued that environmental regulators imposed rules on fisherman without consulting with those whom the policies would affect most dramatically.

"Regulations have defied common sense and are costing fisherman their livelihood," Ayotte said.

"This is a great and noble trade, and many have fished our waters for generations. Maybe the bureaucrats in the Obama administration don't understand that, but thank God Mitt Romney does," she added.
