Elon Musk’s July 5 announcement that he’s starting a new political party could be consequential, but only if the world’s richest man maintains a sustained interest in the effort.

Elon Musk said he's launching a new political party, following through with his threat to challenge the two-party system after President Trump signed the "big, beautiful bill."

Building a viable new political party to rival the Democrats and Republicans is enormously difficult and expensive. Small wonder it hasn’t been done.
