Obama says you’ll be able to keep your existing plan and there will be no changes to your coverage but we know he’s not familiar with the details of the bills, so what he’s saying has no basis in reality.
Here’s an article by an editor at CNN Money who has read through the bills and knows what’s in them and has found five freedoms we’ll lose if these bills become law (except for Congress and the President, of course, who will be exempted from the rules and regulations of the bill for the rest of their lives — I guess some animals are more equal than others).

If you prize choosing your own cardiologist or urologist under your company’s Preferred Provider Organization plan (PPO), if your employer rewards your non-smoking, healthy lifestyle with reduced premiums, if you love the bargain Health Savings Account (HSA) that insures you just for the essentials, or if you simply take comfort in the freedom to spend your own money for a policy that covers the newest drugs and diagnostic tests — you may be shocked to learn that you could lose all of those good things under the rules proposed in the two bills that herald a health-care revolution.

Go read the rest of the article for the details of how this bill comes between you and your doctor, inserting the government in your healthcare decisions.
But those in Texas don’t have to worry if Perry is still your governor come 2010 because he plans to fight:

Gov. Rick Perry, raising the specter of a showdown with the Obama administration, suggested Thursday that he would consider invoking states’ rights protections under the 10th Amendment to resist the president’s healthcare plan, which he said would be “disastrous” for Texas.

“I think you’ll hear states and governors standing up and saying ‘no’ to this type of encroachment on the states with their healthcare,” Perry said. “So my hope is that we never have to have that stand-up. But I’m certainly willing and ready for the fight if this administration continues to try to force their very expansive government philosophy down our collective throats.”

If he wins this battle, Texas will become a very popular state.
