So, this whole government shutdown? Republicans have had it planned for a while:

With polls showing Americans deeply divided over the law, conservatives believe that the public is behind them. Although the law’s opponents say that shutting down the government was not their objective, the activists anticipated that a shutdown could occur — and worked with members of the Tea Party caucus in Congress who were excited about drawing a red line against a law they despise.

A defunding “tool kit” created in early September included talking points for the question, “What happens when you shut down the government and you are blamed for it?” The suggested answer was the one House Republicans give today: “We are simply calling to fund the entire government except for the Affordable Care Act/Obamacare.”
Partisan politics. So effective.
