Again, so what? DACA shouldn't even be an issue. The Republicans are using this for political purposes. For reference, see the ad that Trump's Campaign Committee released.
Yes, because the Republicans are trying to get the Democrats to vote for s budget while giving them nothing. Holding the lives of 700,000 people hostage for politics is disgusting.
This is purely politics from The Republicans.
Now they can screw the Dreamers, and blame the Democrats for a government shutdown. It's baffling that people are falling for it.
Also, the President can remove the protections, but it's morally reprehensible, and he has repeatedly said he wants them to stay. Trump and Republican leadership are the ones who rejected a bipartisan compromise. Trump is the one who didn't negotiate in good faith at the meeting where he said that we don;t need any immigrants form Africa, or Haiti, but need people from Norway.
I don't know how I can be more clear, Trump and the Republicans have poisoned the well, and are not arguing in good faith. You are completely ignoring this as if it's irrelevant. But, it's the entire crux of the issue.
