 Going against the grain as a Republican and supporting Democrat Joe Biden for president is not easy. But I'm not looking at this election through the lens of being a Republican. I'm looking through the lens of being an American. Also, as we hear from Matt Piper, the rules in place for tonight are unlike ever before. I'm Matt Piper. The debate is 90 minutes with just two commercials. And there are ground rules. Mics will be muted throughout the debate, except for the candidate whose turn it is to speak.
