Blackmail.

I thought that blackmail was illegal and you could be arrested for it. But apparently not if you are a member of Congress! 
If this were to work and extremists only had to say, defund Obama care or we will shut down the government,  what does that say about us? Even the crazy African governments don't do that. The next thing could be Millionaires pay no tax or we shut down the government, or pay all Republican politicians $1 million or we shut down the government, teach our kids that the world is 6,000 years old, do virtually anything, or we shut down the government. What kind of a way is that to act?
Just saying.
Incidentally I don't think that Democrats have ever done anything like this. It is absolute insanity.
