there is some mandatory sequestration that kicks in as a result of the 2011 budget control act (which should be abolished), but anything that's worth funding is protected from it, with the apparent exception of medicare, which has been undergoing 2% cuts for years as a result of it. this only results from spending on specific, core government functions, which they seem to think should be restricted for some reason.
but, sequestration has never occurred due to paygo and has never occurred due to discretionary spending and there's no reason at all to think it ever will.
i support the filibuster.
but, they should abolish the bca - and should abolish this obscure paygo thing along with it.
