Maine Morning Star - Collectively, the group of nearly 100 billionaires and spouses has donated $9.8 million to the Collins network since the start of 2025, representing a third of what groups supporting Collins raised from all donors. The total from billionaires stands in stark contrast with the fundraising of her opponent, Democrat Graham Platner, whose campaign has mostly attracted smaller amounts of funds but from many more people. Platner, who won his party’s primary election Tuesday, has received at least $24,000 from five billionaires, a fraction of 1 percent of his total haul.
