Americans on Medicaid exceed population of the UK by more than 10 million

I would've qualified for the Medicaid expansion, but since Corbett rejected it, I fell into the coverage gap instead.

Are you certain?  There are some people who would have qualified for Medicaid had their state expanded coverage, but who are eligible for the subsidies anyway.  If you're in the 100% to 138% of the FPL range, you are eligible for the subsidies, tho it's too late to enroll this year.

Given that if the Democrats had enacted single-payer rather than Romneycare at the federal level, you'd have coverage right now, I think that sort of answers your snide remark in and of itself.

Please name the 60 senators who would vote for single payer.

Or even 51 senators if there were no filibuster.
