Elon Musk's political shake-up with his new America First party proposal has been the latest move in a very public feud with US President Donald Trump.

But how serious is Musk, and could the tech tycoon shift the two-party system in the States, changing American politics forever?

After a two-to-one vote in favour of a third political party following a poll on his social media platform X, asking the question, "Is it time to create a new political party in America that actually represents the 80 per cent in the middle?" Musk created America First.

His bitter rival, Trump, brandished the creation as "ridiculous", adding: "It's always been a two-party system, and I think starting a third party just adds to the confusion."

A YouGov poll stated that 45 per cent of Americans thought a third party was "necessary".

However, pollster James Johnson is unconvinced that the Tesla owner can cause a shake-up in US politics.

Speaking to GB News, Johnson said: "I was digging through the history of this, and there's no party, third party, with as broad a base as his that has ever broken through in the history of America.

"You have to go back to the 1890s to find a third party that had success in Congress. It was the populous bunch of farmers."

Johnson explained that the strict two-party system in the States has dominated over the course of its 236-year history, and a "very broad offering" has never been successful.

Musk does have finances and fame on his side, but the actual organisation of a political party may prove too complex.

Johnson said: "We all know Elon Musk has a lot of money, but we are talking 10s of billions here of investment.

"You wonder about how much the Tesla board is going to freak out, and then you put the history alongside it, and I can't help but think that this is something they're probably not going to be talking about in a year's time."

JL Partner recently polled a Musk third-party to receive four per cent of the vote, with five per cent coming from Republicans and only one per cent from Democrats.

Johnson commented: "People in the UK, there is a feeling that the two main parties are too similar, but in the US, people don't really feel that, because the two main parties are very broad."

Political analyst Scott Lucas disagrees with Johnson's perspective, emphasising that "it's not a political stunt", and Musk can cause a shift in US politics if he plays his cards right.

Lucas explained to GB News: "He's got money, he's got influence, he's got a social media platform, but what he doesn't have is the White House.

"So he's going to be up against all the money that's around Trump, that section of the Republican party that is there working with Trump and all the activists that are around him."

Lucas noted that Musk "wants to be involved" in politics, given his comments about European affairs, particularly here in the UK.

The tech tycoon previously appeared to endorse Rupert Lowe's "political movement" and has been openly commenting on politics in Germany and Italy.

Former advisor to Bill Clinton, Jim Kennedy, discussed how Musk could gather up enough votes to create an impact.

Speaking to GB News, Kennedy said: "You could patch together a majority by creating a candidate who tastes sort of the best parts of both the Republican and Democratic parties and offers that to the people. There is something of a silent majority to be found by the right candidate."

Being born in South Africa, Musk will be unable to run for President as the US Constitution explicitly states that only "natural-born" US citizens are eligible - the challenge he faces will be finding the best nominee.

Looking at what has driven Musk to this point goes beyond his ongoing feud with Trump.

Lucas explained: "What led him to break from Trump, I believe, boils down to two beliefs. I think the first and perhaps the most important is his belief, which is shared by some Republicans, that the level of Government debt is not sustainable.

"Trump's 'Big Beautiful Bill' increases Government debt by such a significant amount, taking it up to $5trillion (£3.775billion) over the next decade. There is a case to be made that the legislation is flawed."

The second area that could have led to Musk's breakaway is with renewable energy, which the Tesla owner has "a direct interest" in.

Lucas said: "Of course, his focus comes in with renewable sources for electric vehicles. But beyond that, Musk's argument is that the United States is falling way behind China in the pursuit of renewable energy, and that Trump's Bill makes the issue even worse."

What could also be spurring the X owner on is recent polling showing Trump's popularity dropping week on week.

According to Reuters and Ipsos polling, the US President's approval rating has fallen to just 40 per cent, the lowest of his second term.

Time will tell, but the ongoing public feud is guaranteed to throw more curveballs.
