The House just completed a successful vote to defund Obamacare for now. There is no chance Harry Reid will bring it to the floor for debate, much less a vote, but that would be a blessing amidst the chaos if he would. The only way he will is if the American people exert enough pressure, but the media won't play it up enough so that most folks will even know it happened.
There is a democratic majority in the senate. They will never get the necessary votes to pass it.
