Support for expunging records of non-violent marijuana convicts is similarly high at 74 percent. This also includes majorities across the political spectrum: 63 percent of Republicans, 74 percent of Independents and 85 percent of Democrats. data for Progress also asked respondents about marijuana banking reform, listing several key provisions of the House-passed Secure and Fair Enforcement (SAFE) Banking Act. Again, each component received majority support, including allowing the cannabis industry to use the traditional banking system (72 percent), ensuring that these businesses are not discriminated against in financial services (77 percent), and protecting the eligibility of cannabis industry workers for home loans (73 percent).
