Elon Musk’s “America Party,” may not have much success, but voters’ dissatisfaction with the major parties is very real.

Mr. Musk’s involvement in politics and his financial support for the president’s campaign were once seen by investors as a benefit to Tesla, fueling a steep rise in company shares after the election last year. That association has now turned into a liability. Tesla shares are down 40 percent from their peak in December.

Elon Musk isn't done with politics just yet. Days after the SpaceX and Tesla CEO threatened to form his own political party as an alternative to America's "Democrat-Republican uniparty," Musk has announced his pledge to do so.

Ross Gerber, a longtime Tesla investor and vocal Musk critic, didn’t hold back online, writing in his own post that, “no one wants the Elon first party,” accusing the company’s board of being “Elon vampires sucking the blood of Tesla equity.”

Tesla stock price fell Monday after Musk said he's formed the America Party, the latest development in the billionaire's feud with President Trump.
