WASHINGTON (CNN) - Republicans rode into power in the House in large part on an anti-Obamacare wave.
That's why they've voted to try and repeal or dismantle the Health Care Act some 40 times over the past three years.
However, now they’re taking it up many notches, bowing to conservative pressure to keep the government running only if Obamacare is defunded.
The way the House Speaker John Boehner tells it, this is not about shutting down the government. “Our goal here is to cut spending and to protect the American people from Obamacare. It's as simple as that.”
Except there is nothing simple about it.
The Government is set to run out of money in less than 2 weeks on September 30th. A House GOP bill to keep the Government funded would also defund Obamacare.
It’s a strategy GOP grass roots groups spent all summer pounding rank and file republicans to support.
“Absolutely heard from a lot of our conservative groups over the break about defunding Obamacare,” said Rep. Lee Terry, (R) Nebraska.
Reporter: The pressure was there, you felt it? Rep. Terry rplied, “Oh the pressure was absolutely there, but none of us like Obamacare.”
The senate is run by democrats who do like Obamacare. That's why GOP leaders privately resisted defunding it on a must-pass spending bill, risking a government shutdown.
Thanks to conservative pressure, Boehner could not find votes to keep the government running, without also stripping out health care money.
Reporter: I know it's not been easy to be the Speaker over this caucus, but at this point, have you just kind of lost control over the caucus?
“Listen, we've got a lot of divergent opinions in the caucus and the key to any leadership job is to listen.” Boehner replied. “We listened to our colleagues over the course of the last week. We have a plan that they're happy with. We're going forward.”
Not all republicans seem happy.
Reporter: Do you think it's a good idea? Rep. Peter King, (R) New York, “We'll see how it goes. We can't let the government shut down. We can't be kamikazes and we can't be General Custer.”
Senate Democrats argue if the government shuts down over trying to dismantle Obamacare, Republicans will get the blame.
“If they think we're going to back off they're wrong. They're on a different planet,” said Sen. Chuck Schumer, (D) New York.
They may have unlikely allies: some conservative senators.
“The only effective way to truly stop Obamacare, and I think we ought to do it, to stop it, would be to totally reverse it,” said Sen. Tom Coburn, (R) Oklahoma, “We don't have the votes to do that.”
