Are most Pro-life Christians against single-payer healthcare?

Here is something I’m trying to understand in the American context: Why are some people who consider themselves Christian, believers of the sanctity of human life, against single-payer healthcare? Is it possible that they believe in life’s right to exist but don’t believe in life’s right to persist, to be extended when our technology makes it possible? Well you can argue that without single-payer people still have the right of access to healthcare, though they may not have the means to afford it. To which I would say: if you consider yourself a Christian were does it stay the sanctity of human life when you let someone die earlier by not being able to afford proper healthcare! In the same logic, how can someone be in favor of postviability abortion following the argument that the mother’s freedom to choose is superior to the baby’s life, and still argue that sick people’s right to live is superior to tax payers freedom to do what they want with their modern-slavery-fruits (aka salary).

Isn’t it more coherent for Pro-life people, especially when christian, to be in favor of single-payer healthcare? Or am I getting it wrong? What do you think?
