I agree that if he did actually rape her (I have a few reasons to doubt she did, but since rape is probably very traumatic, she would probably be ashamed and want to keep it a secret) then he shouldn't be allowed to run.
Of course we can now expect Annoying Orange supporters to viciously harass her because they have done so (like when Donald made rude remarks at Megyn Kelly)
Annoying Orange really isn't fit to be president. Sure he can appeal to half the country, but 99% of this country would not be fit to run for president. I'm not saying centrist presidents are the best, but I think for now they are our best option, as much as I'd like Sanders to win.
