And end gerrymandering at the state level. Picking Michigan as I'm familiar with it, there's a ridiculous bias in the state legislature toward Republicans. Comparing the 2006 and 2010 state senate races is probably the best comparison. In 2006, the popular vote was 55% R and 45% D, with the reverse in 2010. In 2006, a 10% lead toward Republicans gave Republicans a 26 to 12 majority in the state senate. In 2010, a 10% lead toward Democrats gave Republicans a 21 to 17 majority in the state senate. These maps were found by a federal court to be illegally gerrymandered in 2019, but unfortunately, was overruled following similar cases at the Supreme Court[2][3] that year.
