Here's the question exactly how it was asked:
Now I am going to tell you more about the health care plan that President Obama supports and please tell me whether you would favor or oppose it.
The plan requires that health insurance companies cover people with pre-existing medical conditions. It also requires all but the smallest employers to provide health coverage for their employees, or pay a percentage of their payroll to help fund coverage for the uninsured. Families and individuals with lower- and middle-incomes would receive tax credits to help them afford insurance coverage. Some of the funding for this plan would come from raising taxes on wealthier Americans.
Do you favor or oppose this plan? (IF "FAVOR/OPPOSE," ASK

And do you strongly or only somewhat (favor/oppose) this plan?
