Well there are the pro-immigrant story notes, the race bending casting and so on - those things all played to social justice / left groups & probably helped win people over in marketing the thing (having the interest of the PoTUS does tend to help your production get noticed for instance). But none of that would have mattered if it wasn’t any good.

It’s pointless to try and ram the founding fathers into any kind of modern left/right axis - 300 years ago is definitely another country & they did things differently there. Trust me, if you haven’t heard it, get a hold of the cast album and give it a listen. It’s worth your time.
