The Democrats won’t do it without the Republicans sticking their necks out; they’ll just scream that they “can’t” do it without the cooperation of the Republicans. Then they’ll beat Boehner black and blue for “obstructionism”. Boehner and McConnell won’t loudly ‘SPLAIN it to the people; and it’ll be the “mean old Republicans” again and “Bush’s” fault.
Well, if they don’t announce anything and just do it at vote time, then the Dems will have caught the hot potato. What can they do, “uncast” their vote?
