In a politically charged appearance, billionaire tech executive Elon Musk took to the stage with former President Donald Trump on Saturday, casting the 2024 presidential election as pivotal for the future of democracy in America.

Speaking to a packed crowd in Butler, Pennsylvania, Musk, the CEO of Tesla, SpaceX, and owner of X (formerly Twitter), issued a dire warning: “This will be the last election” if Trump doesn’t win.

Musk, who wore a black “Make America Great Again” cap, further intensified his rhetoric by labeling himself “Dark MAGA,” a nod to his unwavering support for the Republican nominee.

This marked Musk’s first public appearance at one of Trump’s signature rallies, underscoring the increasingly visible alliance between the two influential figures.

Musk sought to portray Trump as a champion of free speech, arguing that Democrats want “to take away your freedom of speech, they want to take away your right to bear arms, they want to take away your fight to vote, effectively.”

He was particularly critical of California’s efforts to ban voter ID requirements, portraying such measures as threats to personal liberty and American democracy.

The rally, held on the same grounds where Trump survived an assassination attempt in July, carried a somber undertone.
