The IRA?
The ACA was more or less Romneycare, a Republican idea, but ironically passed with zero Republican votes. The ACA was a permanent government subsidy to the very health insurance companies that people hated and continue to hate, as evidenced by the recent celebration over the murder of a health insurance CEO. The ACA has not resulted in universal health care. It has not ended medical debt and bankruptcy. It has not ended the practice of claim denial. It has not controlled health insurance premium costs, which have surpassed the inflation rate despite bad inflation in recent years.
In any case, the question of the extent to which candidates keep their promises is not particularly interesting, because even their policy proposals are contolled by their campaign donors. Fundamental changes in the system are rarely on the table. The disparity of wealth in the US has continued to grow unabated over the past 50 years, through Democratic and Republican presidencies.
> they realize in the event that repealing the enormously popular policy they ran against would have enormous blowback for them. Repealing Roe is one example.
Um, they succeeded at that. Roe was overturned by Supreme Court justices appointed by Republican presidents.
