This Michael Flynn scenario is more troublesome than a Dreamer being arrested.

If it turns out that the Trump administration were really involved in political espionage, then you can expect the next 2-4 years to be chaos with nothing much getting done in government, and then possible collateral happening to programs...like DACA being secretly shut down...because no one would be talking about it.

And then a Trump impeachment would leave us with Pence...oh geezus...
