No, as I said, the point is to portray Roberts as such a staunch gay supporter that he would take his perspective to the court to overturn the people's vote. As such they create a figure, which I described previously, who would be forsaken by his own party
If the "they" you're referring to are the liberals, then the only outcome of this gambit, if successful, would be a more conservative nominee. Bush certainly wouldn't nominate a more liberal nominee if Roberts is rejected for being too liberal. I think you need to think your theory over.
