Probably just me, but I think Slotkin should consider dropping out and running for reelection instead.
If Harper runs a progressive enough campaign, she will lose the primary, as black voters+progressives is enough to win the primary.
Not a chance. He’ll be lucky to crack 10% in the primary.
A point I've made before is there's this bizarre mindset that Democrats are just as obsessed with celebrity candidates as Republicans are when with the obvious exception of Al Franken, it's very difficult to come up with any examples of them nominating one. If we include professional athletes you could count Colin Allred, but he was nominated largely on his legal work and work with the Obama Administration instead of his sports career. After that the only example I can think of is John Hall who played in some B-tier yacht rock band that was mildly popular in the 70s and served two terms as very generic D backbencher in the House from 2007-2011.
I suspect this is because celebrities and entertainers are much more likely to be liberals/democrats, and are often vocal about politics and causes, but don't run for office, and a celebrity speaking out in support of a liberal cause is so common that people generally just ignore it (aside from the usual suspects like Tucker Carlson or Jesse Waters). Meanwhile because it's more rare for celebrities to be republicans/conservatives, they get more attention and support from their side, and thus encouragement to run for office.
