Assuming health care passes today, there is nothing stopping them. They will go for broke. Expect immigration reform, union check-off and cap and trade to be pushed through before the November election.
I grew up in a city with a predominantly Hispanic population. The place was an absolute rat hole when I left and it has actually managed to get worse. Yet the democrats never get voted out. You can shoot people in the streets there if you are a democrat and still get reelected.
All of the Spanish immigrants that were worth anything and were hard working left. What is left there are exactly what they want to give amnesty to. A bunch of low life jack asses who don't think that they should work for anything and think that the government is there to take care of them. They essentially bring their third world country over with them.
Stay in your third world country if that is what you intend to do!
