"It was nothing but courageous." That is how Mike Rogers explains the Haley Stevens switch, one day before Michigan votes.

Rogers says Stevens asked Abdul El-Sayed to disavow an ad she saw as racist. He refused, and told her she was not welcome in his campaign anymore. That, Rogers says, is what sent her over the edge.

She is still voting Democrat on the rest of the ticket. But in this one race, Rogers says, Abdul is so extreme that she could not do it.

Another Detroit Democrat came out the same way today. Stevens crossed over, Clarke crossed over, and Detroit Democrats keep coming. Watch how many more there are by tomorrow.
