I think because Gavin is an early front-runner for the nomination we will be hearing a lot about his "centrist" credentials. As I said, it's hard for a Governor to actually run away from actual policies and governance.
It looks a lot like he will try to pick a lane that is something along the lines of "Fights back against Trump, but is a pragmatic moderate" or something.
Will he pull it off?
I am doubtful, but that seems to be what he's aiming for.
I'm glad you brought up the spectrum. The challenge is where do we put Gavin relative to his likely competition. Granted, he's no Bernie Sanders or AOC. He might even be more centrist than Kamala (who I don't think has a chance). I would use your political opportunist description for Pritzker. I can't see a billionaire becoming a standard bearer for the progressive left, but he seems to think it can be done.
I think Gavin's far more of an opportunist than I've seen from Pritzker.
Pritzker is absolutely going to get pushback from some wings of the party just by running as "the good billionaire" (or some version of that).
I don't know where he would try and frame himself in a national run and I think you are right that to some degree, the framing will depend on who else is in the running. \
Now is Gavin really more centrist than Shapiro, Whitmer and Moore? I hear Andy Beshear is contemplating a run. Beshear would be a bonafide centrist in the Democratic primaries but perhaps not likely to win the nomination.
I think there is not a lot of policy daylight between all those people.
It will be a question of specific priorities and the sort of rhetoric they use.
The one I can't personally put my finger on is Pete Buttigieg. He has spoke a lot and is articulate. Bonus, he doesn't have much of a record he needs to defend unlike Gavin. He could be a real wild card who can swing left or center-left depending on the audience.
Buttigieg hasn't had to put down a lot of policy, so he may well cast himself anywhere he sees an open lane.
