The boss of the electric car maker Tesla and the space company SpaceX added that "hard-core Democrats or Republicans" would never vote for the other party anyway. That is why it is independent voters who will decide on future majorities. In the congressional elections on Tuesday, President Joe Biden's Democrats are threatened with losing their majorities in the Senate and House of Representatives to the opposition Republicans of ex-head of state Donald Trump.

Musk said in May that he had voted for the Democrats in the past but would vote for the Republicans from now on. At the time, the richest man in the world explained that the Democrats had become a "party of division and hatred" and that he "can no longer support them".

The quarrelsome multi-billionaire bought Twitter for 44 billion dollars (around 44.2 billion euros) at the end of October. He had announced months earlier that he wanted to leave Trump, who was banned from Twitter after the Capitol storming on January 6, 2021, on the platform.

Critics fear that Musk could drastically limit the fight against the spread of hate speech and fake news on Twitter. Those fears were fueled by the firing of around half the Twitter workforce last week.
