The brief détente between Elon Musk and President Donald Trump took its last breath over the weekend, as the billionaire and once top Republican donor announced he would form a new political party.

Here's what it would take for Elon Musk to launch a third-party effort to represent what he called "the 80% in the middle."

Musk promised to campaign against Republicans who voted for the bill, and Trump pondered whether to deport the South Africa-born billionaire.
