An article cited that if the baucaus bill is passed that the insurance Companies could be looking at an increase of their profits by $900 Billion over the 10 years ( I can't find the article but would love to cite it. It starts with the modest assumption of a $250 premium to reach that number) 
Combine this with the Supreme Courts apparent rush to over turn any limitations on corporate financing of campaigns in the Citizens United case ( the Hillary Movie). A case where the bush wingnut appointees created the issue of the Constitutionality of corporate campaign limitations out of this air and required a rehearing of the case to overturn 90 years of precedents.
Combine the 2 issues where the insurance companies will have an endless supply of new cash and no limits on how they can spend it in the political arena and we are looking at the United States of Aetna.
With an entrenched, relatively, young 5 vote majority of ideologues on the Supreme Court coupled with a Democratic president who appears to be too scared of the right wing to appoint any person that George Bush would not approve of in any legal/ judicial post (Examples; Sotomayor is a right of Center Jurist who was on Gw's list. Most of the AUSA's are holdovers from the Bush Justice department. Holder is tripping over himself to pass out Get Out of Jail cards to any rethuglican who broke the law.) and we might as well hand over the what little is left to the insurance companies.
How long will restrictions applying to state and local races stand when the SC opens the floodgates of corporate funds on the national level? This is a case, like Gore v. Bush, where the "Tenthers' will argue against states rights in favor of federal rules.
Any mandate must be stopped. It is not just our money that we would be handing over to the insurance companies it would be whatever thin shreds of political power that remains in the citizenry's hand that we would be surrendering as well.
