From Digby's Hullabaloo, according to a Kaiser Family Foundation (KFF) poll, a majority of Democrats, Independents and Republicans favor a Medicare buy-in plan for adults 50 and older and a Medicaid buy-in plan for individuals who don’t receive health coverage through their employer.

Democrats and Independents also favor a national health plan similar to Medicare for anyone, but would allow people to keep their existing coverage as well as a Medicare for all plan. Republicans polled don't go for these options, but are almost there (47%) for the Medicare for anyone but not required.

Interesting how 56% of those polled favor Medicare for all, but then if it requires paying more taxes those in favor drops to 37%. It could be how the question is asked, as with any poll. If you get Medicare for all and do not have to pay insurance premiums, then wouldn't you expect that taxes would have to be raised to pay for the plan? Otherwise, you will be paying premiums to the government. Either way you'll have to pay, I think.
