Michael Barone runs through some poll numbers for Senate races in Ohio and Connecticut, not good news for Democrats. He asks: "Is the health care issue hurting Democrats in key Senate races? Sure looks like it."  And the proof is the latest Gallup Poll: "More Americans now say it is not the federal government's responsibility to make sure all Americans have healthcare coverage (50%) than say it is (47%). This is a first since Gallup began tracking this question, and a significant shift from as recently as three years ago, when two-thirds said ensuring healthcare coverage was the government's responsibility."
