Reviewing: Tulsi Gabbard
Her campaign site is does not have much information.
Education
Free College
Sponsored the College for All Act which would make college free everyone attending community college and free for low and middle income students at 4 year public colleges.
Cancel Student Debt
Nothing specific on website besides supporting a bill to discharge student loan debt in bankruptcy.
Economy
Tax the Rich
Not mentioned on her site.
Living Wage
Co-sponsored the Raise the Wage Act to raise the minimum wage to $15 an hour.
Healthcare
I support a single-payer system that will allow individuals to access private insurance if they choose.
This seems to suggest she does not support single payer but she has co-sponsored the Medicare for All Act of 2019.
