Romney lost because of Romney... Who he is.... He is a nice man.... He is not in anyway connected to the American voter.... He could not connect with them and they are the primary voters.
Its not about physical cliffs, or taxes, and foreign affairs. Governing is about people and their lives. Romney and the Romenies in the GOP are more than jut out-of-touch with most American citizens, They are not part of this fabric. The Dems also but they at talk the talk.
Search as you might and be politically astute the GOP can't fool this group of voters and they are always the final winning votes.
