"The President said his plan would .... require insurance companies cover check-ups and preventative care..... and prevent them from denying you coverage because of your medical history."
These are two of the exact reasons why health insurance is so ridiculously expensive.
If Obama was sincere in his desire to reform health insurance and the cost of healthcare in the United States, he would be pushing for health insurance to be exactly the same as any other insurance: It pays for unforeseen, MAJOR illness, and people with pre-existing conditions are covered only for those claims not relating to that condition.
Just because YOU have diabetes or have had a heart attack shouldn't mean that an insurer has to take a hit to their bottom line by covering you the same as everyone else.
Bad ideas
