Much like a child who throws tantrums, and whose parents have given into tantrums in the past, once the parents stop giving in to the tantrums and holds firm, the child will have an “extinction burst” of the tantrum behavior trying to see if continuing to do what used to work to get what they wanted will still work.
Since Republicans are really all petulant children who never grew up, it stands to reason that they are doing an extinction burst of behavior that worked in the past, trying to get past results.
They are ignoring that this stopped working like ten years ago.
