VALID reason to vote Trump?

I watched the CNN presdential townhall with Anderson Cooper and watched the full thing , when Donald Trump came on and was asked questions , all he did was mumble and repeat things that didn't even make since. He can't even give any anwser to how he's gonna do the things he says he's going to do!! I'm just wondering if anybody has an actual VALID reason why they would vote for Donald Trump , because I sure as hell can't think of one 😒
