Former astronaut Mark Kelly will run against Republican Martha McSally for Senate in Arizona, saying, “I always knew I was going to serve this country in some way.”

Kelly, who is married to former congresswoman Gabby Giffords, launched his campaign in a video on Tuesday.  He talked about his wife’s near-death experience when she was shot at point-blank range by Jared Loughner outside a Safeway supermarket in Tucson, in a mass shooting. He said, “what do you do when bad things happen, you have to move ahead.” Kelly said his wife taught him “how to use policy to solve problems in people’s lives.”

Kelly said, “We see a retreat from science, data and facts” if we don’t take these issues seriously, we can’t solve these problems” confronting Arizona and the country.

McSally was appointed by Gov. Ducey after Jon Kyl served temporarily after Sen. John McCain passed away. She is considered a vulnerable Republican senate candidate for 2020. She lost against Democrat Krysten Sinema in the 2018 midterm elections.
