Why did Obama (and Dems) vote against this bill if they are so concerned about the solvency of Social Security?

They are not concerned about SS. There only concern is taking care of the poor stupid public that they think are to weak and dumb to take care of themselves. They do not care if they turn our republic into socialism, in fact that is what they want. If they had any sense concerning SS, they never would have voted to take the money out in the first place. They have no real beliefs that go to protecting our Constitution and way of life. So they offer free stuff, that really is not free at all. When abortion was being debated. People were concerned that if it was ped, our tax dollars would go to pay for it. NOOOOOOO, that will NEVER happen they said. We see how that turned out. They then ran on the policy that the govt. should pay for it. "Free" heathcare will be the same way. I have no doubt all the hoor stories we are hearing about it will come true. All this reminds me of our forefathers paying for Manhattan with 24 dollars worth of trinkets. People are stupid that support these people.
