critics arguing that such policies threaten national security, public safety, and the rule of law.

I'd like to see these "critics" enumerate how deportation "threaten":
national security - if anything, catching terrorists enhance nation security
public safety - so getting rid of drunk drivers, criminals, rapists and thieves is bad?
the rule of law - sanctuary cities violates the "rule of law", federally.

Are modern Democrats now again championing the cause of ‘States Rights’ over federal Govt.?
History may not repeat itself, but it sure does rhyme a lot.

The left has a script with effective phrases which elicit emotional responses. If one actually pays attention to what the left is doing, it’s nothing but uttering those phrases, advocating for more of their failed policies, maintaining the status quo, and more spending. Actually accomplishing anything positive for America and Americans is not something they really care about, they just use those scripted responses to give the impression they care.
