Ah yes, the now infamous Beer Summit which became a necessity after Barack Obama knee-jerked accused a White policeman of racism . . . when it turned out that the White Policeman TAUGHT a course on racial equality for the police department.
During the 2008 primaries leftists accused Hillary Clinton supporters of being racist because they did not instantly drop a quasi-experienced Hillary Clinton in favor of a ZERO experienced Barack Obama. That's when huge numbers of life-time Democrats finally walked away from the increasing insanity of the Dem Party.
Trump did pretty much the same thing. The only reason he ran as a Republican is because he knew only Republicans would be stupid enough to vote for him. He said so himself.
Doesn't matter. Dem Party voters don't know their own party's history . . . which is an advantage -- from one perspective -- of being taught in public schools by Cultural Marxist leftist indoctrinated teachers.
