Yes, but I don't think they have done it in this session, with some polls showing Obamacare is more unpopular now than ever before as the bulk of the sh*t is about to hit the fan this coming January.
This new repeal must come with a co-ordinated long-term GOP attack on Obamacare in whatever media the GOP can use, explaining why it was repealed to avoid a disaster and letting even the low-info types understand that the ball is in the court of the Senate 'rats and the Obama White House, and if they don't go along with the repeal, you, the American citizen, might well lose your employer coverage from work or lose your job altogether, etc., etc., etc.
Victory against Obamacare must be won!!!
Thanks for the ping!
