Manchin walked away from No Labels offering him their Presidential ticket.I always thought someone like Manchin had the name and appeal to make a serious effort. Threading the center is more difficult than it looks, but peeling off voters from an aging Biden and a volatile Trump would have made 2024 a good time to give it a shot.
I think there would be a pool of donors for a play in the center.
Either he looked into their organization and saw they were pretty useless or he looked at the numbers and saw he would at best do a Perot run and get double digits and no states.
There is absolutely a massive pool of donors who want someone they consider "centrist".
The media and the mega donor class loves the idea of "Fiscally Conservative, Socially Liberal" but that's the empty quadrant of US voters. (There's very little support for that.)
Outside of their view though, there are probably other "centrist" lanes to run in.
They won't have the big money people lining up, by maybe there are small dollar donors to be found.
But it is too late to build that now - you would have to be working on it for at least a couple of years to make a real run at it.
