The calls started this morning about the NRA ad. The mantra is “No White president’s children having Secret Service protection was ever criticized”. Actually the Bush girls were.
As for the racial suggestions? The problem here is that American minorities have been stripped of their racial pride, by demagogues, seeking to instill hatred & resentment rather than pride in honest effort, in order to control them as voting blocks. Do not fall into the trap of letting them make race--that is human heredity & the continuity of peoples--into something ugly. The ugliness comes in the process of substituting blame & envy for honest effort & pride in personal achievement.
The Left has been pursuing a terribly vicious end game strategy, at least since 2000, and too many Conservatives are playing into their hands, by responses that miss the essential nature of the tactics to which they are responding.
For an argument in point, see Blame & Envy Cocktail.
