WASHINGTON (AP) — Frustrated Democrats lamented Wednesday that persistent problems with new health care exchanges have inflicted damage on the public’s perception of the already unpopular “Obamacare” — with some lawmakers insisting President Barack Obama should ensure those responsible lose their jobs.

Emerging from a closed-door briefing with health officials from the Obama administration, House Democrats appeared to have at least as many questions as answers about how and when the beleaguered website will be fixed. Although they resolved not to let setbacks with one aspect of the health law outshine the parts that are working, they griped that the shoddy website had given Republicans an opening to do just that.
