70% of Independents want universal health care, you don't need to ask centrists, either.

90% of Ds want universal health care.

It's not being stopped by 30% of the voters (Republicans... still, even 30% of them want universal healthcare).

The "pro-universal health care" side is fucking over their own constituents, as they are paid very well to do.

(reminder that independents are now 40% of the voters, Ds and Rs 30% each; these percentages are based on Pew but there are many polls pick your favorite)
