America will be asking itself this question for years after Trump is thrown out of office, because it really was the biggest of fails. We already have some idea of how it happened. Lots of unhappy and marginalized Americans with little knowledge of U.S. history and how America became America is one obvious reason.
But there are likely many more reasons, the likes of which will only be exposed by the results of the multiple criminal investigations Trump is currently facing.
An American president has never been under so many investigations while serving the office. It is so mind-blowing that many just tune this fact out. They just can’t accept it could be true, but it is true and the sooner they accept that we must throw out this lifetime crook for our safety, the better.
