US politics is the politics of decline. From the Zman at theburningplatform.com:
In the year prior to a presidential election, Thanksgiving is usually when primary races for party nominations begin to come into focus. Donors have had most of the year to assess the candidates and the voters are starting to pay attention. The first test is a little over two months away, so all of the candidates have their people in the field. The boots on the ground test is one of those unofficial measures that tell us something about the organic and financial support for each candidate.
According the polls, Mayor Pete Buttigieg is the favorite to win the Iowa caucus, currently polling at 25%. Warren and Sanders are tied for second at a little under 20% each, while Biden is at 12%. The Iowa caucus is not a great predictor, but it does tend to winnow the field. That means the four plausible candidates at the moment are the four at the top of the polls. The rest of the field is in low single digits. Mayor Bloomberg does not appear to be running in the state at this point.
New Hampshire has always been the bellwether and the numbers there tell us it is a four human race as well. The latest polls have Warren, Buttigieg, Sanders and Biden clustered together in the teens. Tulsi Gabbard is the only minor candidate showing any support, which bears watching. New Hampshire has a habit of elevating a minor candidate when the leaders appear weak. Gabbard is the chaos option for frustrated voters in the state. Bloomberg could also be an option.
