That is probably why we did not seen a bigger push for amnesty, even when Obama had 60 Dems in the senate and Pelosi. (I can imagine Bernie Sanders telling Reid his union buddies won't go for it, and Obama telling La Raza "We'll do this after my Stimulus brings the unemployment rate down!")
You know I am always concerned about this, because they never give up, and that includes the GOP when they see an opportunity.
If a Republican becomes POTUS your concern should go to alarm. At least with Obama as president Republicans gut reaction is to say ‘No’.
Dems have learned to push these targeted Dream Act bills rather than the old Bush-McCain amnesty (for all) bills.
