House Democratic leader Hakeem Jeffries had warned Republicans they would come to regret the congressional redistricting fight. And when Democrats counterpunched last month with a victory in Virginia, Jeffries had proved his point. But in a matter of days, back-to-back court rulings wiped out the Democratic gains in Virginia and threatened to erode Black representation by Democrats in the Deep South. The shifting political landscape has been a wake-up call for Democrats, who are favored to win back the House this November. It's also a test for Jeffries, who is in line to become House speaker if his party regains power.
