The Impact Redistricting Has On Who Controls The U.S. House
Democrats dominated the House of Representatives for much of the 20th century but in 1994 that dominance was reversed in the so-called Republican Revolution.
Since then, Republicans have controlled congress more often than not and occasionally even without majority support from voters.
Three key factors have played a role, partisan realignment among the states, especially the shift from Democrat to Republican in the greater south, the nationalization of U.S. politics and a good bit of gerrymandering, that is drawing congressional district lines that favor one party over the other.
We take a bird’s eye view of the makeup of the U.S. House over the past three decades and what that portends going forward.
