This is actually a great strategy
Northam disavowed Latino Victorys bombshell ad as lacking civility, and the group pulled it from the air under pressure. Still, it got more attention than any other ad in the campaign, yet in the end, Northam wasnt hurt by it. And after the returns came in, Adam Jentleson, the rapid-response director for the Center for American Progress Action Fund, defended the ad on Twitter: [M]aybe Republicans have helped create [a] climate of fear. And maybe saying so isnt out of bounds. The president of Latino Victory Fund, Cristóbal J. Alex, took his own victory lap, and suggested more provocative ads are to come. He told Buzzfeed the ad was designed to raise Latino voters awareness of Gillespies bigoted campaign tactics, and it accomplished that goal
we threw a jab to the throat and we will continue raising our voices wherever and whenever racism rears its head."
Of course, its quite possible that the combination of tactics proved complementary. An outside group fired the culture war blast, while the candidate managed, however awkwardly, to stay out of the firing line.

Our candidates take the high road while outside groups dirty up the Deplorables.
