I'm not sure paying Gruber to author and sell Obamacare while, on the other hand, holding him up a some independent outside expert is simply a thought crime. I'm betting there some actual criminality there, somewhere and, it should be investigated.
For instance, were there any Democratic Senators that voted in favor of the bill based on information given them by Jonathan Gruber? It would only take one. Surely you recall all the backroom finagling Obama had to do to get the votes for this piece of crap legislation. How many of the Democratic Senators espoused their support, based on Gruber assurances and, in effect, perpetuated the ruse? Some of the videos I posted demonstrate how heavily Gruber was relied upon by those hoping to persuade the rest of us to buy into Obamacare. Combine Gruber's escapades with other
Congressional payoffs and I think there is sufficient grounds to question the legitimacy of the entire law.
That aside, not all "legal ramifications" are criminal. I think Gruber, particularly, could be subject to some civil litigation over the misrepresentations.
