"Campaigns are fun. Campaigns are police escorts, they're airplanes, they're crowds, they're balloons, they're bands, a lot of fun. You speak in vague generalities. You get applause for slogans. And then governing comes. And governing is tedious and it's difficult an it's time-consuming and it demands your attention. And policy isn't vague generalities. It's specifics and it's based on knowledge."
