The GOP is being pressured by their corporate paymasters to pass immigration reform, especially doubling the guest worker program and almost tripling legal immigration. These were part of the Gang of 8 bill. I suspect and fear that the GOPe will pass something this session prior to the midterms. It will set off a firestorm of protests among conservatives and dampen turnout in 2014. It will force GOP congressmen to go on record for these phony reforms, which will hurt the American worker by taking away jobs and depressing wages. The GOP is not called the Stupid Party for nothing.
Recall a post here about Issa proposing two house bills:
1) Pure enforcement
2) Visas for immigrants with high tech skills
Nothing looking like amnesty.
There is not much that Dems can do with those.
Boehner (or Ryan) taking just those two to conference and coming back with completely different bills (amnesty for illegals) and putting them up for Dem votes strikes me as near zero Chance, but I know its a popular conspiracy theory here.
You are right about Dems see it as a wedge issue, but few in house GOP want to give Obama anything now.
