There's a lot to unpack in this article, I encourage you all to actually read it. It sounds like a fundamental disconnect between Republican Congresspeople (who enact laws at the Federal level) and the State-level Republicans. These Senators supported overturning Roe specifically did it to "send the matter back to the States", and did not propose any law at the Federal level to replace it, only to find that those Republican states enacted extremely strict laws that are now affecting the Republican brand elsewhere. (Because of a simple reason: Republicans in those states really are that extreme!)
But, they're stuck with it now. Their messaging is tied to what actually happened in those states. And these Senators can say all they want that they wanted exceptions all along, but you know they will never make a Federal law that weakens the strict bans in those states. They would never win a primary after that. But the strict bans are not popular outside the statehouses where they were enacted.
As long as there are states like Texas, who aim to criminalize abortion to the point that they will be monitoring the roads going out-of-state for pregnant women to harass, there will be no chance to define the pro-life movement as anything else.
