Axios reports Elon Musk is preparing a large-scale investment to boost Republican turnout in the US midterm elections by restarting his previously paused super PAC, America PAC. The PAC, which spent more than $260m in 2024 to support Trump, will focus on door-to-door canvassing, digital advertising and direct mail to mobilise the conservative base, including voters who typically skip non-presidential elections. Musk’s representatives declined to disclose spending; given his 2024 donations the outlay is expected to be substantial. The report says the move would widen the Republican funding advantage over Democrats and notes Trump’s weak support on economic issues and the Iran war has increased the risk the GOP may struggle to retain House and Senate majorities on Nov. 3.
