The one-plot summary of what Elon Musk did to Twitter.
This is where it gets wild 👇
In 2020, Twitter use was highest among people who loved Democrats and disliked Republicans.
By 2024, it completely flipped: the more polarized Republican you are, the more you use Twitter/X.
From blue stronghold → red megaphone. All for just $44 billion.
