Naw.....he serves a purpose for the Democrat party.
If he was a serious socialist, hed run commercials of himself in coveralls in the hot sun pulling turnips with his fellow comrades at Turnip Commune #34.
Hes just there to draw peoples attention.

If the Dems were rational, they'd let President Trump have four more years, clean out the old garbage from the party, and get reasonable moderates in place.
But the DNC and The Swamp aren't rational. If they finagle the nomination from Bernie, they could have serious uprisings to contend with.
