I do understand something of the long history of immigration problems and Congress' inability to act.  I was referring to the policy decision to end DACA as the problem--we all agree that it was that decision that made DACA a burning issue of the day.  But of course that couldn't have happened if Obama hadn't created DACA, and Obama wouldn't have created DACA if Congress had fashioned immigration laws that were enforceable and reflected a coherent vision of the US's place in the world, and Congress would have been able to fashion a workable immigration law if ...

But the important thing is to look ahead to a rosy future for the DACA kids.  Thanks for supporting that vision.
