john kasich is an uncivilized and bigoted right-wing extremist that the democrats should not be reaching out to, as a temporary ally, however temporary. his views on abortion, queer rights, climate change and a zillion other things should be clearly and thoroughly denounced by the party, and the person responsible for giving him a platform should resign.
unfortunately, as they allowed john kasich to speak at their convention, that means that the democrats must be endorsing his policies on abortion, climate change, queer rights, etc. otherwise, they wouldn't have given a platform to his bigotry.
