Absolutely wrong about Dems and Big Pharm, my friend. Dead wrong. Single payer and public option were the leading Dem proposals, but they could not withstand Repub opposition: they never had a large enough majority to pass both houses: in case you forgot, Ted Kennedy died before anything was done. Unlike Repubs, Dems tried to be inclusive and that took precious time.
I'm sure you're a Dem since you're for single-payer? It, unfortunately, is a partisan issue. You do know Repubs tried to scuttle what we have now and which, though not perfect, is a damn site better than what it replaced. 
Democratic support is growing for single-payer now that Repubs who control both houses FAILED miserably. 
I love when Repubs are shown to be fools; suddenly, they cry for non-partisanship and seek to find some sort of false equivalence, i.e. Dems didn't pass single-payer!
Next you'll blame Dems for the ridiculous budget item of Trump's: 1.6 BILLION for the wall he promised would cost taxpayers nothin.'
