Eric Holder, who served as Barack Obama's Attorney General and now runs the National Democratic Redistricting Committee, has railed for years over Republican gerrymandering of House seats. He claims that Republicans "debase and dishonor" our democracy by the way they draw congressional districts.
We hate gerrymandering and the process that allows politicians to choose their voters, rather than the voters choosing the politicians. Both parties have turned gerrymandering into an art form. There's no reason that computers with random number generators can't draw the lines with no political interference.
But what ISN'T true is the idea that the Republicans owe their House majority due to gerrymandering.
Harvard law professor Nicholas Stephanopoulos and political scientist Chris Warshaw have shown that in the 2022 and 2024 elections "the House exhibited no pro-Republican lean at all. Of course, Republicans won narrow majorities in 2022 and 2024. But they did so because they won narrow pluralities of the total House vote."
In 2024 the GOP won 51.4% of the two-party popular vote but only netted 50.6% of the actual seats.
