Congressional Budget Office: Premiums to double under Trumpcare

[martybegan]

How does the CBO know what the effects of "Trumpcare" would be given the details haven't been released?

The CBO doesn't "know" anything. The CBO is a government calculator, that makes no judgement on the inputs given to it, and just goes through the math to produce results of questionable veracity.

The CBO is defined by the old programming concept of GIGO, Garbage In, Garbage Out.

That is a right-wing myth that keep gets regurgitated, but it's not true.

CBO does it's best to inform the Congress and American public of expected policy outcomes.

For example this is CBO defining minimal considered-coverage standard :

How Does CBO Define and Estimate Health Insurance Coverage for People Under Age 65?

You cannot "feed" CBO your own standard so it will give an estimate you want on coverage.

It's a predictive calculator, that can only use the constraints given to it by the people feeding it data. Plus, reading your article they even hedge what they are producing further, due to the required estimating of certain categories and definitions.

GIGO.
