In their fourth consecutive match-up, Democrat Carol Shea-Porter settled the score with political rival Frank Guinta, beating the Republican Tuesday.
Shea-Porter now heads back to Congress for her fourth term. She served two consecutive terms from 2006 to 2010, and when Guinta knocked her out, she ran again and won in 2012.
The race was called early Wednesday morning, winning the race by a 44-43 margin.
Independent Shawn O'Connor finished with about 9 percent of the vote.
