That reminds me of a survey that found that in the entire field of Social Psychology, there was something like eight people that indicated they would vote for Romney over Obama.
Romney was even pretty centrist, to the point that Obamacare was based on Romney's plan. A similar analogy would be if only a half dozen employees in some field were willing to vote for Fetterman.
At this point I wouldn't consider Romney "rightwing", more of a centrist by current standards. Heck, the president probably thinks Romney is a socialist.
