Alternate-universe Scott Walker, probably.
Not sure I get this answer. Why would an alternate-universe Scott Walker be a Republican abortion doctor?
You think he really cares about abortion? His "pro-life"-ism is just red meat for the rural/populist base.
"Alternate-universe Scott Walker" is a person from some upper-middle-class suburb somewhere who is a hardcore fiscal conservative and capitalist, and who really doesn't personally care about social issues or "morality" much at all as long as he can make lots of money and the rich keep getting richer. Such is the nature of R-WI.
