I want to think that ass quality doesn't matter, but on further reflection I'm not sure. Being attractive helps with election results, although not as much as you'd think. Just a few percentage points, according to the studies I could find. All the studies I found were face-focused; afaict nobody has done a political ass analysis. It might be unscientific to extrapolate. https://www.pnas.org/doi/10.1073/pnas.0705435104
