NASHUA, N.H. (AP) — President Barack Obama is seeking to win over voters in low-tax New Hampshire by criticizing Mitt Romney for raising taxes and fees when he was governor of neighboring Massachusetts.

Obama says Romney is making "a lot of last-minute promises." But he says the policies the Republican is pushing are the same ones the Democratic campaign contends hurt the middle class in Massachusetts.

The president says Romney even tried to raise fees in Massachusetts on getting a birth certificate, "which would have been expensive for me." It was a veiled reference those who have incorrectly claimed Obama was born outside the United States.

Obama spoke to about 8,500 people at an outdoor rally on an unseasonably warm October day in New England.
