Back in mid-April, I crunched a bunch of numbers and concluded that around 6.5 million people enrolled in unsubsidized ACA-compliant individual market policies are, on average, paying an additional $960/year ($80/month) for their policies this year due specifically to last year's sabotage efforts by Donald Trump and Congressional Republicans. This is separate from other factors such as medical trend and the reinstatement of the ACA carrier tax. The actual 2018 "Trump Tax" ranges from as little as almost nothing at all in Vermont and North Dakota to as high as $1,500 per enrollee in Mississippi and Pennsylvania.
The 2018 sabotage impact was mainly due to 1) CSR reimbursement funding being cut off; 2) uncertainty over individual mandate enforcement; and 3) a mish-mash of Open Enrollment changes including cutting the time window in half, slashing marketing/assistance budgets by 90% and 40% respectively and so forth.
A few days ago I noted that I had seriously misunderstood the Congressional Budget Office's individual market premium projections in the event the ACA's individual mandate is repealed: Yes, it'd be ugly, but not nearly as bad as I thought, although they still expect up to 13 million people to lose coverage as a result.
While I have my own doubts about some of the CBO's assumptions, there can be no doubt that premiums would increase substantailly, millions of people would end up without healthcare coverage, and the $25 billion in Medicare cuts do appear to be locked in if the GOP's bill were to become law:
