Political insider turns anti-incumbent table on 8-year Dem in key Senate race: 'Hasn't delivered'

CONCORD, N.H. - A Republican running to flip a blue Senate seat in a crucial battleground state is flipping the script on the Democrats' anti-incumbent argument.

Former Sen. John E. Sununu, the GOP Senate nominee who's running to return to Capitol Hill after 18 years away, charges that his Democratic rival, Rep. Chris Pappas, has "been in Washington for 8 years and hasn't delivered for New Hampshire."

Sununu and Pappas are facing off in the midterm election in the battle to succeed retiring longtime Democratic Sen.
