WASHINGTON (AP) - Signaling he'd meet critics part way on health care, President Barack Obama said Tuesday he's willing to sign a bill even if it doesn't deliver everything he pursued through a year of grinding effort at risk of going down as a dismal failure. The Democrats' massive health overhaul legislation is stalled in Congress by disagreements within the party and the loss last month of their 60th Senate vote, and with it, control of the agenda. Republicans suspect that Obama's invitation to a televised health care summit Feb. 25 is a thinly disguised political trap. On Tuesday, the president tried to change the dour dynamic, indicating he could settle for less in order to move ahead.
