I'm not sure "No Social Security Cuts" should count, because (1) he did try to cut it in his proposed 2020 budget, (2) he did nothing to try to address the shortfall that is expected in the social security trust fund around 2033, and (3) he said that if he was reelected in 2020 he would get rid of the payroll tax, which would have moved the depletion of the trust fund up to around 2026.
