I have no idea how you guys come up with this shit.
It is easy, Coach. When you look back at previous Presidential campaign promises and then look at how those promises played out during the elected Presidents time in office, you will find that often the results are disappointing. It does make some difference who is President of the U.S. it just doesn't make as much of a difference as people think it does. Keep I'm mind, the President is not a dictator, he has powers but not the absolute power to change things as some people either think or hope he does.
My prediction is that if Obama is elected for another term, he won't achieve all he has promised in his campaign speeches. If Romney is elected President tomorrow, he also will not live up to all of his campaign promises. This is just reality. Actually, it is fascinating how passionate and invested we all are in these elections. Never-the-less, one must vote because to not vote at all is to give up and that should never happen.
