In a setting where others would willingly lie to prevent the persons hiring? It's not even a question. Handing a virtual veto to anyone that wants to make a sexual misconduct claim is nothing short of insane. There absolutely has to be evidence. In this latest claim there is nothing, it's not as compelling as a rumor.
Let's look at it another way, let's make it personal. What if it was you who was on the chopping block? What if someone at the company Kwanzaa party that didn't like you said you touched them inappropriately? Would you agree the accuser has to be believed? Would you hang your head in shame and walk out the door a ruined man? We both know the answer to that, we both know that there are innumerable people that would make any claim necessary to keep a republican off the bench.
This is 100% political. No one actually gives a fuck about what an idiot kid did back in college, no one gives a fuck if someone wore black face at a halloween party, or said great person 50 years ago. This is simply another weapon in the political arsenal, a reason to fake some outrage and point a trembling finger at the vile evil doer.
To answer your final question, Kavaughna's chance of being a sexual predator is exactly the same as your's or mine, it's 50/50 for everyone that hasn't been convicted.
