From FiveThirtyEight, showing the percentage answering “more” to the question “Providing health insurance for people who do not already have it–should the federal government spend more on it, the same as now, less, or no money at all?” in a 2004 poll. Note that the colors show deviation from the U.S. average, which was 73% answering “more”; brown indicates lower support, turquoise is higher support:

Not surprisingly, higher income correlates with lower support for more spending to cover the uninsured. The lower support among those over age 65, compared to other age groups, is sort of fascinating given that they themselves benefit from government spending on health programs that provide them coverage. But then, given that I’ve seen photos of people holding signs saying “keep the government out of Medicare,” I don’t know why I think people on Medicare would support public health insurance in general.

Of course, these numbers have likely changed now that the health care issue is getting so much coverage and publicity.
