We absolutely do have minority rule. In both the Senate and the House, the Republican majorities represent a minority of the population.
The fact that both the House and Senate are nearly 50% by party again points to the fact that we have a good balance.
The fact that we have minority rule in the Senate, House, and Supreme Court is exactly why we don't have any checks and balances any more and Trump gets to act like an emperor.
It seems clear that the majority in the 2024 election preferred Republican governance, and so they gained control over President/House/Senate.
Obviously I understand that not every person voted in the election (many are not even eligible). It is simply not relevant to this conversation, and is an often trotted out diversion meant to diminish the mandate given by the actual voters.
