So Djou is denouncing the spending of PAC's on third party ads that...effectively...help...him.

So is Caldwell, kinda. 

It'd be real noble of them to tell them in the same breath "Now, please stop these commercials". Saying that statement would actually be progress in this campaign that has now degenerated into one side chiding the other side with a "shame on you" phrase. 

Sorry to burst the bubble and return us to reality, but one of the few rules that is left in politics is "don't look gift horses in the mouth".
