Washington (CNN)President Barack Obama is taking an unprecedented step into down-ballot races in the final two weeks before the 2016 election.

The outgoing Democratic president is set to endorse 150 state legislative candidates — part of an effort to flip Republican-controlled state legislatures across the country ahead of the 2020 redistricting battle.
The endorsements will come in the form of TV and radio ads, mailers, recorded calls and statements.
