> Who was the last president with integrity?

Integrity not to burn down the system and/or enrich themselves? All of them: Biden, Obama, Bush43, Clinton, Bush41, etc (maybe Nixon the least). If Hillary Clinton or Harris would were elected they would have been as well.

You may be disagree with their policies, and think perhaps they're helping certain special interest groups, but has anyone tried to enrich themselves while in office (versus book deals and speaking fees once they're out)?

*more integrity. that would make anyone i guess more qualified
