> ~half the country doesn't think ICE should be locking up tourists without good reason and the other ~half doesn't think ICE should be locking up anyone
That is not remotely a good faith representation of the controversy.
I've lived my entire adult life in the USA (international student -> non-immigrant temp worker -> resident -> citizen). People are delusional if they think the USA is split in half about immigration. The anti-immigrant sentiment among whites, blacks and some naturalized immigrants (like Cubans in FL) is truly the only thing that crosses political boundaries here.
