Obamacare was designed by the Democratic controlled Congress, Pelosi and Reid in charge  and signed by President Obama.  It is theirs, warts and all.

No Republican voted for it.  

They cut the deals on drugs and insurance and the penalties for not being a participant.   They designed it so the increase in Medicaid payments to Oregon is going to be reduced by 10% after Obama leaves office and the penalties go up after he leaves office.

It hasn't been amended since so they are on the hook for all of it.
