"Historic" or traditional patterns don't seem to be fitting this election as in the past. I was waiting to see how long it would be before voters discovered Amy Klobuchar. She picked up some recognition in Iowa, next door to her home state, by making a lot of appearances but the caucus format there didn't help her out much. She surged in New Hampshire and that will open the door to more money and exposure.
It's hard to say how decisive this primary will be, except that Biden and Warren are probably headed out. It's down to Sanders, Buttigieg, Klobuchar and Bloomberg. I'm OK with any of them.
There is not going to be a Democratic constituency that sits this election out, especially not African Americans or Latinos. Noting that all of the remaining Democrats in the field except Tulsi Gabbard have leads over Trump in head to head polling, including Steyer, this is going to be a turnout election and the Democratic nominee will pick up around 55% of the popular vote and more than 325 electoral votes.
