She got the school mams

As part of Harris’ first sweeping policy announcement of the race, she also will highlight that black teachers earn $2,700 less annually than white teachers — and that women make $2,000 less than their male counterparts.
Overall, the average teacher earns $1,000 less than they did 30 years ago adjusted for inflation, according to her campaign.
Harris’ proposal, which follows several highly publicized teachers strikes that have roiled cities, allows her to broaden her economic message beyond a tax plan that would give monthly cash payments of up to $500 to lower-income Americans.
Harris’ teacher pay plan, the first of its kind from anyone in the field, also will give her new entree to a professional field dominated by politically active women — after she expressed solidarity with their ranks during strikes in Oakland, Denver and Los Angeles.

Her natural base. She can trade it at the convention and teachers might get some federal goodie.  A lot of big ifs.
