You know Prosser as the "WMC Justice." Wisconsin Manufacturers & Commerce put about $6 million into his campaign. They spent like drunken sailors on leave. But they were not drunk; they knew what they were purchasing and so do you.
I have no idea what he's talking about. Ten years ago, Justice Prosser ran unopposed. I suspect that no one "poured" any nontrivial amount of money into a walkover. This year he is opposed, but it seems highly unlikely that anyone - let alone WMC - has spent anywhere near six million dollars on the race. Perhaps someone will (although there is not a lot of time left to do it), but it sure doesn't seem to have happened yet.
I have asked Garvey to substantiate his claim. If he can, I'll link to it here.
