Right.  I can read.  The Hart - Cellar Act "changed the way quotas were allocated" meaning there is a limit, per country on how many visa applications would be issued.  It also "created preference visa categories" which also translates into further restrictions.  That's why your argument regarding race, religion, national origin is specious.  Straw man, if you will.  Because no matter how the left spins it, our Pres. has the Constitutional authority codified in law to further restrict as he sees fit according to 8 US Code subsection 1182.  "Supercede"?  Hmm...it looks more like amended to me cuz it still kept provisions from 1924, 1952, and enhanced/elaborated on specific verbage; especially the part about visa denials to what are now considered protected classes.  So you see how we read the law and then interpret what it says...Doug & Watson aren't doing that.
