They have grown much closer even since Nadar made that comment. I think that we would live in a different country today if Gore had taken the office he won. I don't believe we'll live in a different country if Romney wins instead of Obama...there is one exception and that is the Supreme Court. IT's enough for me to vote for Obama, but frankly, I don't think it's unrealistic to say these guys have grown very close.
Even if we assume for purposes of argument that Romney and Obama are the same, if Romney wins instead of Obama that will mean that in all likelihood we will have a Republican-controlled White House, Senate and House of Representatives. It is insane to think that what comes out of D.C. under those conditions would be the same as what would come of of D.C. if Obama wins.
