Well what Trump learned from that is that conspiracy theories work better if you don't actually investigate them. It is exactly why there have been 0 investigations in "Spygate", or anything to do with Hillary Clinton. Vast amounts of undefined voter fraud really only works if you don't look at voting hard enough to notice that it isn't there.
If I tell you there is a monster under your bed, it doesn't behoove me encourage you to look under your bed.
