These are hardcore #NeverTrump protesters who are rabid Sanders supporters, backed by Soros‘ MoveOn and other socialist communist groups. These protesters aren’t too smart either as they invoke their First Amendment right to protest and speak freely while desecrating the Flag that provides the very freedom they abuse! The hypocrisy cannot even be measured.
These radicals want to start a fight at every Trump rally because they know many who attend are very angry to say the least. They are more or less throwing gasoline on a fire, that said imagine how things will play out in Cleveland and Philly this year. Prepare for chaos especially if the establishment selects candidates against the will of republican and democrat voters.
