Read the full Washington Post-ABC News story

Serving up more bad news for Hillary Clinton, a Washington Post-ABC News poll conducted Feb.16-20 shows Clinton in a statistical tie with Barack Obama at 48 percent to 47 percent, and leading him in Ohio 50 percent to 43 percent. The margin of error in both states is 4 percent.

The new poll squares with other polls that have bubbled up over the last week, in which the Texas race has been narrowing to a dead heat, while Clinton’s once-big advantage in Ohio has dwindled. At the same time, Clinton and Obama are in the same close horse race in national polls released today.

The poll says that the economy and health care vie for the top spot among voter concerns, while health care is the clear cut issue in Texas where, according to a Wall Street Journal column, 25 percent of the people are uninsured, the highest of any state.
