Yes. Why should anyone expect otherwise?

People in poor health often have more immediate concerns --- like maybe making it to the bathroom on their own.

Standing in line to vote may not be a realistic option.

Totally agreed. It would be unreasonable to expect otherwise.

That said, now that there’s more formal evidence of it, we’re in a better place to ask questions like “what are the systemic effects of that on policy?” and “are we okay with those effects?” and “what do we want to do about it?”

Also because voters probably have better education.

Why study that direction? What about being in good health increasing the likelihood of voting?

That said it surely is something else leading to both.
