U.S. Senate candidate Richard Mourdock sent a “thank you” email to supporters a few days after his Nov. 6 election loss to Joe Donnelly.

“I remain incredibly appreciative of our volunteers, supporters and every person who entrusted me with their vote,” Indiana’s Republican state treasurer wrote.

He included a P.S. under his name.

“We fought until the polls closed on Tuesday. Unfortunately, this left our campaign in debt. Anything you can do to help us retire our debt is appreciated,” Mourdock wrote.

Mourdock had more than $1.1 million in available cash to spend in the last weeks of his campaign against Rep. Donnelly, D-2nd, according to a pre-election finance report Mourdock filed Oct. 25 with the Federal Election Commission.

Throughout his run for a Senate seat, Mourdock criticized President Obama and Congress for increasing the federal budget deficit and the national debt.
