President Obama used a campaign-style trip to Texas on Wednesday to rally liberals on his sputtering health care law, calling it a system of "universal health care" and calling out Texas Republicans for, he said, denying health insurance to 1 million state residents. For decades, liberals have dreamed of a "universal health care" system in America and Mr. Obama used that phrase, which he rarely does, in telling a group of volunteers that, under his leadership, it has become a reality.
