Why would Boehner say something like this? Is he expecting a partial vote down? Or Obama to usurp the Supreme Court by dictate and assume the rest of the Congress will do nothing? Why say “if we win, don’t be happy”?
No, he is doing it, a bit ham-handedly, because it is an election year and he is terrified of offending independents - the group of voters that will choose the next President and the makeup of the House and Senate.
They are, at the danger of offending them, a bunch of Rodney King "let's all get along" ninnies and sissies and get their panties in a wad if Republicans start acting "partisan". That's why he's doing it, he needs the votes of that cohort in order to win. That's why Democrats always try to bait the Republicans into something they can claim is "partisan"...because the independents piss all over themselves when they hear that.
Yet, those numb nuts actually decide the elections. What a frickin' mess this country has become.
