But it is the Democratic Party that never ceases to celebrate diversity — racial, religious, ethnic, cultural — as its own and as America's "greatest strength."

Understandably so, for the party is home to a multitude of minorities.

It is the domain of the LGBTQ movement. In presidential elections, Democrats win 70 percent of Hispanics, Jews and Asian-Americans, and 90 percent of African-Americans.

Yet, lately, the party seems to be careening into a virtual war of all against all.

Democratic Governor Ralph Northam and Attorney General Mark Herring of Virginia have both admitted to using blackface.

Northam imitated Michael Jackson's "moonwalk" in a 1984 dance contest. Herring, in 1980 at the University of Virginia, did a blackface impression of rap icon Kurtis Blow, who called it ugly and degrading.
