Stack what court? I would reference FDR if you'd like a primer on stacking the Supreme Court. How'd that work out for him?

However, Republicans have slowly found a way around stacking. They just nominate far right justices. It's about overturning precedent.
Confirming judges with far right beliefs (while espousing "moderate" views during their confirmation process) who will rule with the
hand of God....while also taking influence peddling from right wing, Christian organizations..even accepting gifts from them. But hey,
it's ok, because it's all for God.
Stacking Congress??? What reality do you live in? Republican legislatures are by far the biggest proponents of redistricting and gerrymandering.
It's all about trying to desperately hold on to power that is slipping away from them in the form of a more multi-racial and multi-cultural country.
