Running State Interference

The Governor has called out the National Guard in Minnesota, not to assist Federal authorities in rounding up criminal aliens but to serve as a blocking force to protect Minnesotans presumably from ICE. Has the failed Vice Presidential candidate ever heard of the American Civil War? The government in Washington, District of Columbia, established primacy by force of law and arms over the States in that bloody conflict. I would contend that States' rights were vanquished then for all time, essentially making it a settled issue, unless some fool wants to relitigate it with bullets and bombs at some point. I have this not necessarily novel notion that cities and states should work with, not against immigration agents to make communities safer.
