I looked at the headline of this thread and thought to myself: how did we get to this point?
I honestly believe that the turning point was when Obama tried to establish eDACA and DAPA.
That's when conservatives really got pissed off and started throwing around buzzwords like "unconstitutional" and "overreach" and "amnesty" made those same words applicable to DACA. I seriously believe that if it wasn't for that moment when Obama tried to get a little too saviouristic, we wouldn't be discussing this right now.
