The realo candidates collectively received more votes than the fundis in Iowa. Should we be encouraged by that?
Not really. The Remain parties got more votes than Leave in the 2019 UK election, and you know how that turned out. The Remain votes were split, and the Conservatives, as I predicted, won a crushing victory.
There is a scenario in which Sanders is running unopposed in the progressive lane by Super Tuesday, and there are three viable candidates still scrapping for realo votes. If that happens, Sanders is probably going to be the nominee, and disaster looms.
The bottom line is that the realo faction needs to pick a single candidate, and stick with him, by Super Tuesday. Period.
