Jennifer-Ruth Green’s campaign has shifted the Democrat stronghold of Indiana’s first congressional district to a “toss-up” election.

The Northwest Indiana district, represented by first-term Democrat Rep. Frank Mrvan, has not sent a Republican candidate to Congress since 1932.

Mrvan made headlines last month after FEC filings showed he spent thousands of dollars in campaign cash on flights and seat upgrades for his wife.

Green, a U.S. Air Force reservist and Iraq War veteran, would be the only black Republican woman in Congress if elected.
