JEFFERSON CITY, Mo. (AP) — Democrats won more votes, regained control of the U.S. House and flipped hundreds of seats in state legislatures during the 2018 elections. It was, by most accounts, a good year for the party.
Yet it wasn't as bad as it could have been for Republicans.
That's because they may have benefited from a built-in advantage in some states, based on how political districts were drawn, that prevented deeper losses or helped them hold on to power, according to a mathematical analysis by The Associated Press.
