Given the basic dynamics of the catfood commission: Republicans don't need a 'win' but Dems do and Republicans won't support any tax increases except maybe regressive ones, there's a good chance that come December that they will come out with a "compromise" which will include raising the Social Security retirement age. Why Dems think a political winner will be destroying their one remaining brand, basically the most popular thing the government does, and opening themselves up for attack ads stating, truthfully, "Congressman X voted to raise your retirement age..." I do not know.
December will, for us, be the busiest month.
