The fact-checker stuff is silly. Politifact can fact-check anything they like, and given that they're biased towards liberals, they will tend to fact-check those statements by Hillary which are probably true and not fact-check those which are likely to be false.
As for evidence, the op-ed I linked, which was from 20 years ago, laid out in considerable detail evidence of Hillary's dishonesty. You, too, may be too young to know the details, but her behavior during the Whitewater investigations was outrageous. Hiding documents which were under subpoena, committing perjury, suborning perjury. She checked all the boxes. The stuff about her cattle futures trading was particularly laughable. When she realized that the obvious bribe that she accepted might look to the public as if it were a bribe, she concocted a story about how she studied the Wall Street Journal to learn about the cattle futures market, and she was really proud of her trading success. Of course, it was a complete fantasy, not dissimilar from her claim to have come under sniper fire in Bosnia. She probably had no idea what her benefactor was even trading during 10 months when $100,000 of "profits" were racked up.
More recently, of course, her lies have been too numerous even to list. Yes, she's campaigning, and all politicians exaggerate, mislead, or even lie in order to advance their candidacy. But her lies are just so brazen, that it's almost breathtaking.
