@ryanhoulihan My wild guess prediction is Tammy Baldwin. She's in a must-win state like Whitmer, if elected a Dem governor would appoint her replacement, also I think she was the first lesbian elected to the Senate which is pretty badass.
I feel like this undercurrent of "we're spending all our political capital with a woman of color nominee; we have to pick a cishet white dude as the running mate" is just too cynical of a take.
