You had lots of company. I was all in for Trump but I thought the years of ground game prep and 'get out the vote' machinery would push Clinton over the top. It does look like she will win the popular vote.
I was going with Johnson the last couple of weeks. Then I noticed a disconnect between what the media was telling us and I was seeing on the street. Considered a Brexit effect. If it was going to be closer than the media thought, I wanted to ditch Hillary and protect the second amendment.
