The 27 Amendment involves congressional compensation.How does it apply to Obamacare?
THe law changes their access from FEHB to the new state based exchanges which aren't scheduled to come into existence for 4 years.
Any amendment of the provisions in Obamakkkare simply run into the very same problem ~ so changing back to FEHB from state exchanges for the four year period wouldn't allow the law to go into effect any earlier.
