A progressive wing of the Democratic Party in Delaware is endorsing primary opponents to six incumbent Democratic state lawmakers who supported the "billionaires bill", which became law in 2025. The bill was pushed for a change to the state's corporate law that benefits executives and billionaires, including Elon Musk and Mark Zuckerberg, who have faced shareholder litigation in the state. The Working Families Party is endorsing six Democratic candidates in primaries against those who supported SB 21. The party argues that the bill will harm minority shareholders and allow boards and executives to make decisions based on their own interests rather than for the broader investor base.
