I think you missed my point. What you refer to as 'exposing these scumbags' isn't really exposure at all. It comes off as just a hit and run tactic designed to stir the pot….. in fact, Trump even admits that this is all it is since at the same time as he raises the issue, he couches it in the words of ‘other people will bring it up’. The general public already has a fairly jaundiced view of everything that is said out there and when someone says something that could be deemed ‘an outrageous suggestion’ (certainly by the great unwashed who only get their news from talking heads on LSM) and then further distances themselves from the comment by only suggesting that “other people will bring it up but I’m not going there”, it unfortunately starts smelling like a lack credibility. After all, he didn't say he believed it, was leaning in the direction of believing it..... some could even interpret his comments as indicating that he doesn't actually believe it himself. Trump has proved that he can be quite inventive with his campaign and he doesn’t need to undermine himself.
Trump will win the WH because he is smart, fearless, hates PC, and doesn’t listen to the hand-wringing counsels-of-war-that-breeds-timidity political “experts” and advisors.
