It’s not just selective enforcement of immigration laws. Selective exclusion of individual entities from obamacare while forcing everyone else to comply under threat of prosecution is the same principle.
Yes - similar concept - Selective enforcement and selective exclusion (with no basis for the exclusion except political favoritism)... Surly a good set of lawyers could work this into a case in Federal Court.
We have the same selective application of tax laws based on notions of progressivism. The federal income tax was invented by progressives and has been administered by them since 1913.
