INDIANAPOLIS (AP) — New campaign fundraising numbers in the Indiana governor’s race show that Democratic candidate John Gregg has raised more money than incumbent Republican Gov. Mike Pence.

Gregg raised $1.76 million through June 30, about $125,000 more than the $1.63 million collected by Pence. The Indianapolis Star reports that Gregg received a handful of $100,000 to $200,000 donations from regional and national labor unions.

Laura Albright, a political science professor at the University of Indianapolis, says the relatively small difference should concern the governor. She says it’s especially rare that a Democratic challenger in a primarily Republican state would raise more money than the incumbent.

But Pence has over $4.2 million in his campaign coffers, compared to over $1.8 million for Gregg.
