I'm pessimistic nothing will change
You do realize that this means you believe change will occur, don't you?
Look, the fact of the matter is that the man in the big office does have an effect on the average American's life. I'm assuming you're one of these people who believe he is a whole lot rhetoric with no real ideas of experience. He actually was a pretty effective senator. As a senator, he thought big. Bills he introduced were notable for introducing sweeping reform. Last year, he introduced and got more bills passed than both McCain and Clinton. He also regularly recruited more co-sponsors for his bills than Clinton.(Several of Clinton's bills actually had no co-sponsors)
A healthy portion of the bills Clinton introduced were almost nominal: honorary days for veterans, tax rebates.
Obama managed to pass bills of larger scope. His record focused on energy, health care, education and the environment. He introduced and passed more bills than either Clinton or Mccain in these categories. You can easily look up this information on the Library of Congress' website.
You may not like the man, but he has demonstrated that he is a different kind of politician.
I'm curious as to why you would post a quote attributing progress to the unreasonable , then criticize the idea of being unreasonable. I guess your point is too deep for me.
