Wouldn't you see more "mexican-hat" kind of structures everywhere if they were merely rounding to the nearest decimal/decade? In the >= 95% you can see them but otherwise they are absent or less pronounced. Then again I'm no expert. A quick-ish search on Benford's law and election results argues that it is problematic at best to determine fraud in election results. Though every paper I see recommends more research.
