The "centrists" that I know stand on the same ground they stood on 20 years ago. If we're talking about the ideologies then I feel that the right has moved further right, and the left further left, which would leave the centrists about smack dab in the same spot. If we're referring to actual political parties then the left has moved further right too. Biden is not a leftist. Any actual leftists get clobbered by the DNC.
