Updated 6:18 p.m. | The Democratic Senatorial Campaign Committee today released a hard-hitting response ad to Indiana Treasurer Richard Mourdock's controversial comment that pregnancies resulting from rape are "something that God intended to happen."
The committee is spending $1.1 million to air the ad through Election Day.
The spot reminds viewers of the comment and also shows statements indicating that Republicans Mitt Romney and gubernatorial candidate Rep. Mike Pence distanced themselves from the remark.
But the toughest part of the ad is that it splices together Mourdock's comments on rape with an older clip in which Mourdock says, "To me, the highlight of politics, frankly, is to inflict my opinion on someone else."
Roll Call rates this race as a Tossup.

Mourdock's campaign charged that Donnelly broke a rule that forbids the use of debate footage in television commercials. The footage is copywrited by the state's debate commission, according to a Mourdock aide.
"Hoosiers are calling Joe Donnelly's attacks sleazy, and it's no wonder why," Mourdock spokesman Brose McVey said. "Now Donnelly and his liberal Washington allies are attacking Richard Mourdock's faith and beliefs."
