The first woman sworn as a U.S. Senator was a progressive Democrat from Georgia. She was an advocate of prison reform, women's suffrage and educational modernization...
She was also an advocate of lynching blacks as a means to preserve the social order.
Progressive Democrats have always leaned toward themes of class envy, hate and vilification to build their political power base.
Today is no different than a century ago. They've just shifted to target (woo) what they see as an easier manipulated, numerically larger contemporary voter base. But their pandering is just as ugly, hate-based and bigoted today as it was in earlier eras.
