There should really be a redistribution gas tax, another dollar per gallon on gas which then goes back split evenly to every American. Incentivizes less gas usage while avoiding the regressive nature of a sales tax. Canada has something like this.
Ruinous politically so it would never happen but it would be a good plan.
Speaks to character, if you run as a "family values" candidate while cheating on your spouse. It's not inherently disqualifying, especially compared to self identifying as a Nazi, but it's not something that the press or the people should ignore.
"What people do in the sheets" rhetoric is for stuff like kinky sex or being gay...nobody should care if he likes getting pegged. Nobody should care if he has an open relationship. Nobody should care that he likes trans porn, which he said he does. The problem with cheating is the character concern of caring about your wants no matter who it hurts. That is a bad characteristic for a political leader.
