It goes without saying that we need to close our borders. (Trump and Cruz would both do this, of course.) If we don't recover nationalism, we are doomed.
OTOH, patriotism is no guarantee that we will not ruin ourselves through stupid politics. (Many of our most ardent patriots are ignoramuses. A couple of years ago, I met a redneck Democrat who loved Obama--and he explained that the main reason why he liked Obama so much is because Obama is so patriotic, so pro-military, and so pro-firearms.)
The Constitution needs to be defended one way or the other and we are running out of time.
If that means we need a General Grant so be it. I will buy the whiskey.
