Jonah Goldberg, a senior editor at the National Review, inferred in a Friday column that GOP presidential candidate Ben Carson is “more authentically African-American” than President Obama — apparently because the president is only half-black, and didn’t grow up poor and in the hood like Carson. Goldberg clearly thought he had a valid argument and brought it up in a discussion from a broadcast of MSNBC’s “Morning Joe.” The topic of the discussion was on Carson’s appeal and Jonah Goldberg had no issue taking it there.
