It's so hilarious when people compare the polls from the 2016 election to the polls reading the public's approval on #45. You cannot compare because asking someone who they will vote for is entirely different than asking someone if they approve or disapprove of #45 on his current job in office.
You're right. I think even his voters expected him to do a lousy job. They didn't care. They would gladly sacrifice America and their freedom to keep someone with a vagina out of the oval office.
