Medicare

I watched the debates yesterday between President Obama and Mitt Romney. I was very disappointed in President Obama.  He did not seem "there" to me, and wasn't really fighting back. I was so surprised and disappointed.
An issue that I am very interested in is medical insurance.
I am disabled. I have a connective tissue disease, without a specific name or treatment.  I have severe arthritis in my spine and joints.  I have radicular, and ulnar neuropathies. On top of this I also had Endometriosis and Adenomyosis.
I could not wait to get Medicare!  I wasn't happy that all of this was going on, but I had such a problem with my old insurance. This doctor wouldn't accept it. That doctor was enrolled, but wasn't taking more patients. Blue Cross/Blue Shield PPO, made me wait SIX MONTHS before I was allowed to get treated for Endometriosis.  This was right in the middle of having surgeries and being on dangerous medications.  I had to stop everything for six months, because they would not pay for a pre-existing condition.  I knew Medicare would be a great insurance for me.
I was right.
I was enrolled in medicare last year, and had the surgery I needed this year, after finding a doctor to work with. It was a very lucky thing for me to have had the hysterectomy done, as the endometrios was spreading to my liver. It was on my liver already, but no deep adhesion had formed yet, thankfully.
I owe it to Medicare, which enabled me to see the doctors I needed to see, have all the tests done, that I needed to have.
I still have medical issues, but I know what they are. There is no longer a "mystery" as to why my body seems to break down and I feel terrible pain.  I still have the problems with arthrtis and so on, but I am allowed to be on whatever drugs I need. I can get whatever tests I need.
Mitt Romney thinks that private insurance is great?  Private insurance is there to make money off of other peoples illnesses and misfortunes which should NOT be allowed.
I am living proof that Medicare is a great insurance.  Medicare for everyone is a very good idea. 
I am hoping that President Obama comes back to himself, and continues to fight for us.  He fought so hard for this insurance to be passed, yet he seemed absent at the debate.
I am wondering if this idea was truly his. Are any of his ideas real, or is he just reading from a cue card?
