not listening to Trump and what he was saying during his "campaign".  for buying into his hate and fear platform. for rabidly supporting him without thinking through what his "policies" would actually result in. for believing. or wanting to believe , that building a huge wall would serve to cure any of our ills.  to continue to support trump as he runs roughshod over our democracy, heavy-handedly making a huge money grab and pushing us out of his way..
 for continuing to support him in overwhelming indications he has sold us out to curry favor with russia.  for still support him after he showed how absolutely ignorant he is with everyman's life.  still support him after he asks WHO KNEW that HEALTH CARE COULD BE SO EXPENSIVE.
 to support him after knowing that he thinks sexually assaulting women is OK because he is rich. to support him after he has shown he is petty, mean, hateful, a traitor...
 my fingers are pooped - but i think you get the idea. for ignoring all facts and reason
