This chart shows every individual and group rated by PolitiFact at least 50 times, sorted from most to least honest.
Hillary Clinton is the most honest politician they ever rated, followed closely by Obama and Sanders.
Yes, "honest politician" is considered an oxymoron. Yes, we'd love to see a politician with solid green all the way across. Yes, Clinton has exaggerated on a few things, for which PolitiFact has harshly judged her (more harshly, in my opinion, than similar exaggerations by Republicans).
But she is nothing like Liar-in-Chief Donald Trump, whose 51 Pants-on-Fire ratings dwarf the runner-up's 19, both in number and percentage. Michelle Bachmann is the only person with as high a percentage of Pants-on-Fire ratings that is even close to statistically significant.
Trump’s median rating is False! Clinton is one of only three with a median rating of Mostly True.
The average scores shown are based on a scale of 5 for True, 4 for Mostly True, etc.
