And the economic right have had all the power for the last god knows how many election cycles... They've been chasing the unicorn moderate that would somehow vote Democrat, which doesn't exist, but in doing so they lose the "left" vote.
Those "centrists" and "moderates" are conservatives that are disgusted by the GOP, but would never vote for Democrats because they don't agree with their policies. They have no party but the economic right liberals keep trying to attract them... Hopefully now with the change in DNC leadership they'll stop this losing game and actually be what their voters want them to be.
