Companies? I understand the concept of Tort reform was to offer additional protection to doctors. What causes you to make this an issue of company vs individual?
Were this truly just left of center the ratio of those opposed would not be above 60%. Both the rabid left and the rabid right are joined in opposition, although for different reasons. Those outside of these two camps, that are the ones that actually reason a position are almost universally opposed.
An awful lot of poor legislation has been passed and still survives on the promise that we will fix it later. I think many of us have become fed up with this concept and do not want to suffer another round of "fix it later".
Over and above all of that is once the bill is passed then the regulations are written with no input from either Congress or us. This is where the real scary stuff will come from.
Most of the doctors are locked into their insurance plan for a certain period of time so the primary beneficiary of Tort reform in the near future would be the insurance companies.
