WASHINGTON (CNN) – As the prospects for passing health reform by the time Congress leaves for its August recess look bleaker, Democratic grumbling about President Obama is growing louder. One Democratic senator tells CNN congressional Democrats are “baffled,” and another senior Democratic source tells CNN members of the president’s own party are still “frustrated” that they’re not getting more specific direction from him on health care. “We appreciate the rhetoric and his willingness to ratchet up the pressure but what most Democrats on the Hill are looking for is for the president to weigh in and make decisions on outstanding issues. Instead of sending out his people and saying the president isn’t ruling anything out, members would like a little bit of clarity on what he would support – especially on how to pay for his health reform bill,” a senior Democratic congressional source tells CNN. The Democratic leadership had hoped the work going on behind closed doors for months could bear fruit in time for the president’s news conference Wednesday night. But multiple Democratic sources tell CNN that’s looking very unlikely, and one senior Democratic source tells CNN there is some frustration among Democratic leaders that Senate negotiators have, "repeatedly missed deadlines."
