Kamala winning might lead to him dying but it might also lead to him going to prison for fraud and frankly both outcomes would be funny because there's a 99% chance he'd just kill himself in prison.

Kamala winning would also probably lead to Musk doing the funniest thing possible and trying to kill Twitter before he inevitably has to admit defeat and sell it for pennies on the dollar like Yahoo selling tumblr.
