And to tell you the truth, I'm not even sure what "uniting" means.  If the man proposes something that I can support -- even partly, I will support it.  I cannot support his proposals merely because he is president.  There were things that Obama said and did that I did not like and there was MUCH that happened during Clinton's administration that I did not like or support.  
I think that the initiatives of this administration have so far been horrific, and we can talk about specifics, if you like.  I cannot support the Health Care proposal, or the proposed budget, or the sudden bombing of Syria (which made no difference anyway, except for using up fuel and ordinance), or any of the other things that his administration has proposed or done.  If he were to propose what I consider to be rational immigration law reform, I would support it in a heartbeat.
