Senator Tom Harkin (D-Iowa) charges Obama with "beginning the unraveling of Social Security"

65. I told you why they voted against it

Many (if not most) of those who voted against it didn't like how it was funded. Parts of the law were paid for with an increase in federal employees' contribution to their retirement which many progressive members of congress opposed.

Most progressive members of congress voted FOR the bill. That is a fact that you can't get around and have yet to explain, other than you think they caved. Kucinich and Franks caved? Ridiculous. Republicans voted for it for the same reasons Democrats did. They voted for it because it had the overwhelming support from the public. They voted for it because economists said it was a good idea. They voted for it because the struggling economy needs it. They voted for it because it helps those who need it most.

And your claim that "Every progressive public interest group" was against it is just flat out wrong. The Progressive Policy Institute says that only a minority of progressives opposed it on the grounds you claim...

Some progressives (though not many) profess to oppose the payroll tax holiday on grounds that it’s part of a collateral attack on Social Security.

The Center for American Progress, NDN, PPI, and EPI all published several articles that supported the payroll tax holiday.
