- No, members of congress don't always vote the party line (although this has consistently gotten worse over time)
- No, that's not what "balance of powers" means.
“The number of Justices on the Supreme Court changed six times before settling at the present total of nine in 1869”

Stacked in the sense that more members were appointed by one party vs the other (including one by dubious means), and those people apparently are quite partisan.
Partisanship works in the current political environment. Cutting off your own projects in case the other party follows your lead, has paid off more than bipartisanship. Voting across aisles is strictly controlled.
Trump was voted in precisely because The R base was tired of people talking about identity issues, getting to power, and then doing nothing about it.
Trump is giving people exactly what they were told would solve their problems, for decades.
The balance of powers has been broken, for good reason. It ensures political goals - see Bi-partisanship doesn't pay.
