How many different justices do you think were involved in rejecting all those birther suits at the Supreme Court? We know at least five of them are not on your side.
No, they are on YOUR side, along with Roe v Wade and Dred Scott v Sanford. This is called the "sinistra" side.
There is a fundamental difference you keep ignoring.
We know that there are justices that oppose Rowe v Wade. We know that there are prestigious conservative legal organizations that oppose Rowe v Wade. We know that there are conservative politicians that embrace opposition to Rowe v Wade and make its repeals a major campaign issue.
Now - we know of no justices that think Obama is not eligible. We know of no prestigious conservative legal organizations that have publicly stated that Obama is not eligible. And in the middle of a presidential primary, there is not a single conservative politician willing to embrace birtherism.
So your Rowe v Wade analogy does not hold water.
