Most have been bad, starting with John Adams and his "direct tax".

There's a few honest ones. Taft (though he lied about his health, as did others), Kennedy, and I know it's unpopular but I think Carter was honest. Worthless, but honest.

IMO though, the most honest president we've had since George Washington was Gerald Ford. Sure, he lost the subsequent election (wasn't a re-election) but from what I've read he didn't really want the job, and was happy to see it go.

He was republican, but with many moderate views. When you make both sides unhappy, you're probably doing the job right.

I think a national lottery for presidental candidates would be ideal. Lottery picks 6 random citizens age 35-75. Then everyone votes. Electoral College winner gets president. Popular vote winner gets vice president. If the same, the runner up gets it. A single 5 year term, but the process happens every 4 years, so the newbies get a year overlap to learn the job. Get in. Do your job. Get out. Collect a pension. Problem solved.
