I agree with you assessment of Trump; however, even his harshest critics give Trump credit for a lifetime commitment to healthcare for all.
Bernie's Senate bill will probably closely follow one already in the works in the House:
https://www.congress.gov/bill/115th-congress/house-bill/676
"The program is funded: (1) from existing sources of government revenues for health care, (2) by increasing personal income taxes on the top 5% of income earners, (3) by instituting a progressive excise tax on payroll and self-employment income, (4) by instituting a tax on unearned income, and (5) by instituting a tax on stock and bond transactions. Amounts that would have been appropriated for federal public health care programs, including Medicare, Medicaid, and the Children's Health Insurance Program (CHIP), are transferred and appropriated to carry out this bill.
"The program must give employment transition benefits and first priority in retraining and job placement to individuals whose jobs are eliminated due to reduced clerical and administrative work under this bill."
