But when our elected officials and our political campaign become entirely untethered to reason and facts and analysis, when it doesn’t matter what's true and what's not, that makes it all but impossible for us to make good decisions on behalf of future generations. It threatens the values of respect and tolerance that we teach our children and that are the source of America’s strength. It frays the habits of the heart that underpin any civilized society -- because how we operate is not just based on laws, it's based on habits and customs and restraint and respect.
