I voted for Gary Johnson too, because I hated both Clinton and Trump. I felt some excitement on election night 2016, as it marked a change, and I did believe in some things Trump said on the campaign trial. I then gave Trump's presidency far more chances, for far longer, than my liberal peers. I thought Russia-gate was not nearly the conspiracy it was made out to be.
But the last 3 years of Trump's relentless racism, fearmongering, disrespect, and plain old incompetence have turned me against Trump for good. Ukraine-gate was the straw that broke the camel's back; once that story broke, I supported impeachment.
In comparison, whatever Warren did or didn't do regarding her children's education is just not important. The "Fauxcohontas" attack you keep using is a dumb slur that only makes you look foolish. She's already apologized several times for claiming native heritage. There's no evidence that doing so benefited her in any way.
Warren's clearly smart and worked her way up from basically nothing to what she has today -- unlike Trump who inherited a business empire from his dad and has basically coasted off of that for his whole life. He would have made more money through the years if he had liquidated his empire and invested it all in mutual funds.
