Donald Trump's campaign is as divisive as any we have seen in our lifetimes. It is built on stoking mistrust and pitting American against American. It`s there in everything he says and everything he promises to do as president. This man is the nominee of the Party of Abraham Lincoln. We are watching it become the party of Trump. And that`s not just a huge loss for our democracy. It is a threat to it, because Donald Trump`s campaign adds up to an ugly, dangerous message to America.
