Also, where is the RAISE Act?
My guess is that the Democrats know that if they vote for funding the wall in the Senate, Trump will sign the DREAM act.
They can’t be explicitly linked in public, but I’d guess that Paul Ryan knows they’re linked (and he wants to pass the DREAM act too).
Trump is probably insisting on the border wall funds (and mandatory E-Verify) before he’ll agree to sign the DREAM act.
Trump is depending on Democrat votes in the Senate to get the border wall, and I suspect they’ll vote for this, knowing Trump will then approve the DREAM act.
Neither side can get what they want without cooperating, and it’s a classic political trade-off. Trump gets the wall, Democrats get the DREAM act, and Paul Ryan looks like he can get things done in the house (the 2018 elections are coming :)
