Democrats don’t run on issues, unlike most in the GOP, because they either have none or they are bad ones. They run by destroying their opponents in good Alinsky form: “identify, personalize, polarize”. Obama won the 20012 election not on his record, which was awful to say the least. He won by turning Romney into a worse version of Montgomery Burns from The Simpsons: an evil money-grubbing plutocrat.
Now they are at it again: Trump is “unhinged, racist, bigoted”. There is virtually no discussion on policy, because the Democratic platform has been a miserable failure. But Trump appears to be doing the same to Clinton: “liar, criminal, corrupt”. The only difference is all of Trump’s pejoratives for Hillary are provably true. We’ll see which side wins. It may be Trump’s only chance.
