Mark Bradley and I have been friends for 25 years, and we have worked together on more than a few Republican campaigns. He's the issues wonk; I'm the word guy. For years, Mark and I have been daring each other. I've been challenging him to put his name on a ballot — something I recommend all Americans do at least once in their lives (yes, I've had my turn) — while Mark has been daring me to change my political affiliation from Republican to Independent. I'm still waiting for him to run for something, but last Friday I made the leap from "R" to "I."
