(Radio Iowa) –  The Democratic candidates in Iowa’s first and second congressional districts say the line to maintaining a Democratic majority in the U.S. House runs through Iowa. Liz Mathis of Hiawatha, the Democrat running in Iowa’s second congressional district, and fellow Democrat Christina Bohannan, the first district candidate, rallied with supporters at a “county line” fundraiser near Lisbon this weekend. Bohannan is from Iowa City. “We are standing on the line between two of the most competitive congressional districts in this country, so this is ground zero for this election in every way that matters,” Bohannan said.

Mathis told the crowd it’s go time. “We’ve got to get out the vote,” Mathis said. “In this district, district number two, we have only now 2700 or so more active Democratic voter registrations than Republican.” This spring, Mathis and Bohannan were among a dozen candidates national Democrats identified as top prospects for defeating Republican incumbents. Mathis is challenging first-term Republican Ashley Hinson of Marion and Bohanann is challenging Republican Mariannette Miller-Meeks of Ottumwa, who’s also in her first term in the U.S.

Election Day is 64 days away.
