He wasn’t campaigning there, but Michael Bloomberg won the Iowa caucus. No one scored a knock out victory. This leaves the door wide open for Bloomberg. In fact, it could not have worked out better.
Nationally, he polls just behind Joe Biden and Bernie Sanders. Pete Buttigieg did well in Iowa and might do well in New Hampshire, but he has no support among minorities. After Super Tuesday, it could well turn out to be a Bernie / Bloomberg Battle.
If they can keep from criticizing each other too hard, they might even be able to team up. Bernie for president, Bloomberg for VP. Wouldn’t that be interesting . . .
