“New Hampshire hasn’t elected a Republican Senator in 16 years but Democrats are now at risk of losing a seat to the scion of a political dynasty, jeopardizing their chances of controlling the upper chamber,” Bloomberg reports.“Voters from both parties will head to the polls on Tuesday to pick their nominees to replace Democratic Senator Jeanne Shaheen, who decided not to run again. The leading contender on the Democrat side is U.S. House Representative Chris Pappas. For Republicans, it’s John Sununu, who previously served in the Senate from 2003 to 2009 and whose brother and father were popular New Hampshire governors.”“An unexpected Democratic loss in the Granite State would wipe out a hard-fought midterm victory elsewhere and complicate the party’s chances of securing the net gain of four seats that they need to win a Senate majority.”
