It is massive and I believe vastly underappreciated among Democratic supporters and activists. However worried you are about this, you're not worried enough. David Byler:
"Even after the 1980 election — when Ronald Reagan was first elected president — Democrats still controlled most statehouses: 29 to the Republicans’ 15. The two parties shared power in the few that remained, all in the Midwest and Northeast.
After the 2020 election, the numbers nearly reversed. Republicans control 30 state legislatures, while Democrats hold only 18....
Democrats won the popular vote in every presidential election from 2008 to 2020. But in the states, Democratic control of state legislatures is confined largely to the coasts.
And this picture is unlikely to change anytime soon. Democrats had hoped to gain up to seven legislative chambers in the 2020 election; instead, they lost two in New Hampshire. “The Democrats spend half a billion dollars in state legislative races across the country,” said Chambers, “and said they were going to flip multiple chambers … and they didn’t.”
Bad, bad, bad. Where did all that money go?
