You must give me some quotes from Hannity or Breitbart; I don't visit like you apparently do.

The CBO isn't lying; they're just guessing.  

Pelosi and Reid 'guessed' that Obamacare would be self-sustaining by now; that's why they set up the 5% and 10% reduction now.  

Let's keep this simple.  

Oregon has to spend $270 million more dollars starting July 1, 2017 to cover our increased 5% cost of Obmacare for the next two years.  .

See the article elsewhere on the "News" section of today's R-G.  It is about the "Legislature After Two Months".

In 2020, Oregon has to cover our increased 10% cost  of Obamacare for the next two years.

10% is two times 5%.  Assuming no inflation problems, Two times $270 million is $540 million dollars.

That is called "doubling".  

"To be twice as much as:"

"To be increased twofold:" 

We don't have that money unless we a) increase taxes or b) reduce other services from the State of Oregon.
