WASHINGTON (AP) — In a bruising setback, Senate Republican leaders shelved a vote on their prized health care bill Tuesday until at least next month, forced to retreat by a GOP rebellion that left them lacking enough votes to even begin debate. Minutes earlier, McConnell divulged the decision to GOP senators at a private lunch also attended by Vice President Mike Pence and White House chief of staff Reince Priebus. The Congressional Budget Office analysis suggested some ammunition GOP leaders could use, saying the Senate bill would cut federal deficits by $202 billion more over the coming decade than the version the House approved in May. Senate leaders could use some of those additional savings to attract moderate votes by making Medicaid and other provisions more generous, though conservatives would rather use that money to reduce government red ink. The budget office report said the Senate bill's coverage losses would especially affect people between ages 50 and 64, before they qualify for Medicare, and with incomes below 200 percent of the poverty level, or around $30,300 for an individual. The Senate plan would end the tax penalty the law imposes on people who don't buy insurance, in effect erasing Obama's so-called individual mandate, and on larger businesses that don't offer coverage to workers.
