Final answer:
Business owners would not have been a member of the Roosevelt New Deal Democrats.
Step-by-step explanation:
The group that would not have been a member of the Roosevelt New Deal Democrats is business owners. While many different groups supported the New Deal, including African Americans, immigrant factory workers, and Southern farmers, business owners were less likely to support the New Deal. The New Deal introduced regulations and programs that aimed to protect workers' rights, which may have been seen as detrimental to the interests of business owners.
