Democrats are a 100% radicals only party. Working class Democrats in the midwest and south are not going to want a part of it anymore.

Maybe, but I doubt it. Theres still a strong, perhaps pathological, bias to vote Democrat in some rural areas. The roots for this go back to depression era grandparents passed on up the family tree. We see the same condition with American Jews. Evangelical Christians who now vote Republican are their strongest advocates which includes protecting the security of Israel. But, American Jews still vote Democrat. Go figure...
Never say never. Im one of millions of ex-Democrats whove left the party in the last two decades. Trump wouldnt of won Wisconsin, Michigan and Pennsylvania without some Democrat crossovers. We live in our FR bubble here. I think theres more dissatisfaction with working class White Democrats than we know.
