So Much For "Mr. Nice Guy"   During her run for the White House, Hillary Clinton made it clear early on what she thought about half the country.  She called Trump supporters "irredeemable and deplorable."   Joe Biden tried to come across as an old-style moderate, and he's talked a good game about unifying the country.  But now that a number of states are taking measures to rollback pandemic restrictions and reopen their economies, Biden's "Mr. Nice Guy" schtick is gone.    He said lifting restricts now was "a big mistake" and the result of "Neanderthal thinking."
