Bush, assuming he runs as a Republican, is not likely to align himself with the MAGA movement, as he has called President Donald Trump 'personally troubled'. And in December 2023, he donated $50,000 to a super PAC that was in support of Nikki Haley, Trump's main rival in the 2024 Republican primaries. He has not given much to Maine politicians but has supported Senator Susan Collins, a moderate Republican who voted against Trump's Big Beautiful Bill.
