The champions of democracy are suddenly worried about a democratically elected president enacting the will of the people who elected him. Truth is stranger than fiction.
This is a problem of our own creation and we have ignored it for 2 generations by letting immigration law go unenforced and while also not improving the path to citizenship for those who are law abiding and want to be a proper citizen or legal resident. Immigration is the primary wedge issue to drive people apart like abortion has been, but now it doesn't have the same luster because it's no longer a federal issue, but a state one.
