The Senate passed their version of the health care reform bill. "Our challenge, then, is to finish the job," Obama said about the rest of the work that needs to be done to get a final bill on his desk.
That final bill will need to be a merging of the passed house bill and senate bill. If the merge is successful then the bill will just need to be signed by President Obama to become law. That won't happen though until after the new year when Congress is back in session.
Although there are still specifics that the Democrats are trying to agree on to merge both bills, one thing that is probably certain to come about if the merge is successful is the end of insurance companies dropping coverage because of pre-existing conditions or acquiring a disease or other condition. Also, there will probably be no public option and insurance will be mandatory.
