Agree with your post, and would add that there’s WAY too much that can happen between now and November to put any faith in polls at all. Wikileaked emails, terrorist attacks, social media kerfuffles, etc. At best, they are a sign of trends.
I remember when McCain was up 7 points..looking like he would win the election..the second the stock market tanked that was it..game over..no one knows what will happen between now and November anything can happen and change everything
