It is no longer a secret among a few or winked at that Tom is a pathological liar at the DUmp yet skins keeps him there.
I think it goes back to what you have said before regarding what skins thinks of his underlings on the island.
He is happy to let Tom treat them like the fools he himself considers the primitives to be.
Remember, sir, my fellow alum Skins is just doing his job, and doing a great job.
The purpose of Skins's island is to identify, attract, and segregate primitives from the general population of Democrats and liberals, to hide them on a little island so they don't make authentic Democrats and liberals look bad.
Sort of like stuffing Retarded Johnny up in the attic.
By keeping the primitives on Skins's island, they're out of view of the general public.
