The Democrats are the Borg.
Republicans can rarely if ever agree on anything. Getting a majority of Republicans on the same page is almost as futile as herding cats. Nearly impossible.
Democrats have personal agendas. Democrats always, if reluctantly, put their disagreements aside for the party’s ultimate goal of changing the USA into a one-party rule democrat totalitarian gov’t.
The Republicans have no such unifying goal which drives them to capitulate to the overlying objective.
Much harder with such a narrow majority. Even though the worst of the reliably rotten RINOs were primaried away in ‘22, real republicans are individualists enough, with differing versions of purity, that their reaching 100% agreement is rare. And with the majority so small the exceptions plus the group-think Democrats are often a majority. Now, had we won the expected ‘Red Wave’ in ‘22 rather than a red ripple, enough of the republicans might have come together on many issues to leave a majority. Problem is harder in the Senate when there need to be enough republicans to make a 60% supermajority to move many things forward.
