The Democratic Senatorial Campaign Committee on Thursday started a multimillion-dollar ad campaign in New Hampshire that criticizes likely Republican nominee Scott Brown.
The ads, which will run through Election Day, say Scott Brown voted against seniors and to protect oil companies' tax breaks when he was a senator from next-door Massachusetts.
Brown is expected to win his Sept. 9 primary. He will face first-term Senator Jeanne Shaheen, a Democrat.
Shaheen has run ahead of Brown in polls through the summer, although one recent survey showed the race getting closer. That has made Democrats nervous.
Even before the latest ads, Brown has been hammered with negative ads. Outside groups already have spent $2.7 million against him.
