Your essay is excellent.
However I disagree one of your points:
"By electing for Obama as President, the American people have demonstrated that taking risks and keeping an open mind are actually more important than the so called reassuring certainty that a McCain legislation might provide."
People were more driven by the failure of the previous government which to my judgment was determinant of the outcome of the 44th Presidential Election.On the contradictory note of your argument,I will add McCain gave emphasis on being a maverick, and rather than the traditional republican approach asserted on his bipartisan methodology.
That is my outlook.
Thanks and Regards
