President Trump's been tweeting crazy conspiracy nut things for years, like having 'extremely credible sources' saying President Obama is from Africa. Clearly tweeting crazy things doesn't disqualify one from becoming President.

It does disqualify one from becoming a Democratic President, though.

But it should. Trump got through a filtering processes that should have prevented him from becoming president. This is not evidence that we should not filter crazy people out of the electoral process. If anything it’s evidence that the filter needs some work.
