Pennsylvania has seen a rise of Republican voter registrations since tech billionaire Elon Musk offered a financial incentive for people to get swing state voters to sign his pro-Donald Trump Super PAC's petition.

Musk, the richest man in the world with a net worth of $242 billion, according to Forbes, has pledged to give away $1 million a day to voters for signing his political action committee's petition backing the Constitution, a pledge experts say raises legal questions.

Elon Musk has made himself into an influential factor in Donald Trump's reelection campaign, but his ascension hasn't always been smooth.
