One Colorado Republican running for the U.S. Senate this year has a message for voters: He cares. Ken Buck, who is running to challenge incumbent Democrat Mark Udall, has a new ad in a series touting his record of helping people in his role as district attorney of Weld County, north of the Denver area.

The ad features Stephanie Drobny, a woman with two young children who fled an abusive husband in Montana. Drobny describes how Buck, as DA, helped her feel safe and even worked to change a loophole in the law to keep the ex-husband away from her children. Watch the video below:
