I remember 1980 well. Even though I was nearing the end of my 4th year in Germany (how cool was that, spending less than a month of the Carter Administration in the US?), the electoral tsunami that wiped out Carter was felt in Europe.
I'm not feeling it today, and it has nothing to do with Comey. Reagan had a backbone, but he never took personal insults publicly, "there you go again" would be his most remembered, and effective, rejoinder.
Trump and Hillary are both bullies, each with an enemies list that are unrivaled. Both are not liked and not trusted, in equal dollops. That's why I'm not seeing a similar tsunami.
What the heck, I'll throw out my prediction: Hillary wins by 2.5 points in the popular vote, with 325 being the over/under on her electoral vote (won't be a blowout, that's for sure). Won't be enough to turn the Senate back to the Dems, it will be 51-49 Republican, but the House Republicans lose 15 seats.
