👉 The Senate's fluid refers to the ability of senators to shift their votes between the two main factions within the Senate: the majority party and the minority party. This flexibility allows senators to change their stance on legislation or votes based on the issue at hand, party dynamics, or personal relationships, rather than being strictly bound by party lines. This fluidity is crucial for the Senate's function as a deliberative body, enabling compromise and negotiation to pass legislation that might otherwise be blocked by a strict adherence to party discipline.
