I came across the website for the Center for Economic Justice, a Texas-based organization that is trying to help minorities, the poor, and to regulate the insurance industry. They have a report that talks about what really happened as a result of Governor Bush's tort reform. Here's a blurb from their website:

Our reports have established that insurers earned over $2.8 billion in windfall profits in 1996-1998, and that consumers are not reaping the promised benefits of substantially lower insurance premiums. This windfall to insurers has been realized at the expense of consumers, and we continue to expose insurers’ unjust enrichment at consumer expense.

Check the site out and join the group - it's free.
