Obama cannot pass immigration reform without first passing card check. The unions won’t stand for it. Can you imagine the teamsters voting for someone who supported Obama’s immigration reform, so Walmart can legally hire Mexican truckers to haul their Chinese made goods?
I am sure the dems will manage to work all of that out after the midterms are over and they gather for the lame duck session.
They may have nothing to lose.
And it is also quite possible Obama will just forget about Congress and just rule by fiat. He seems to find that quite easy.
