The White House expected a slam-dunk at Thursday's health summit -- another tour-de-force by President Obama that would convince rank-and-file Democrats in Congress that the time's come to push the reform bill through. That didn't happen -- but the push is still on. The president's advisers seemed to expect the Blair House event to repeat President Obama's triumph at last month's House Republican retreat in Baltimore. But there, he was on stage, flanked by flags and behind a microphone and podium looking down on Republicans who were sitting around tables at lunch.
