CONCORD, N.H. — New Hampshire has a long history of electing women, but its tenure as the only state with an all-female delegation in Washington could come to an end after two short years.

Democrats Carol Shea-Porter and Annie Kuster were elected to the U.S. House in 2012, joining Democratic Sen. Jeanne Shaheen and Republican Sen. Kelly Ayotte. At least two of those seats will continue to be held by women after Nov. 4: Ayotte isn’t up for re-election and for the first time two women are running against each other for a New Hampshire congressional seat – Kuster and Republican Marilinda Garcia. But Shea-Porter and Shaheen face male Republican challengers, Frank Guinta and Scott Brown.

Shaheen, the first woman elected governor in New Hampshire and the state’s first female U.S. senator, argues that women can’t trust Brown on equal pay, reproductive rights and access to contraceptives. She has hammered Brown for sponsoring legislation as a state senator that would have required women to be given graphic images of developing fetuses and to wait 24 hours before getting an abortion. Though he won’t say whether he still supports those provisions, Brown argues that his main intention was to promote adoption and insists he is an “independent, pro-choice” Republican.

New Hampshire also was the first state to have a female governor, state Senate president and House speaker at the same time and the first to have a female majority in its state Senate.
