Of course there was vote fraud. There is always vote fraud when Democrats are running for election. In a close race it is decisive, and the Democrats almost always win in close races.
When there is a margin of less than 0.1 percent between candidates, there is no good way to determine a legitimate winner. A new runoff election should be automatically required. It is unfortunately too late to apply such a remedy after-the-fact.
In this particular case, Republicans should adopt the Democrat tactic of demanding recounts until their candidate is declared the winner.
You get into coal country with Donkeys still running voter reg and elections at the county level, handing out pencils instead of pens knowing optically they won't register -- you're talking about once you find 50 ballots that didn't register Bevin, you are off and running. The optix of some poor Appalachia-faced woman crying that 'my vote for Bevin wasn't counted, it was ruin't', and it's on like Donkey Kong.
