The "Roosevelt coalition" or the "new deal coalition" is an alignment of different groups that from 1932 until the late 1960s voted for the Democratic party candidates and supported the New Deal.

The poor got new government jobs and income bonuses. All of them benefited from the revitalized economy that came from the New Deal.
