A new ABC News / Washington Post poll out tonight puts Hillary Clinton and Barack Obama in a dead heat in Texas and Clinton clinging to a single-digit lead in Ohio.

The numbers are 48-47 Clinton in Texas, and 50-43 Clinton in Ohio. Between a quarter and a third of the vote

Says ABC's analysis:

"In Texas, Clinton’s being kept competitive by support from Hispanics; she needs them to turn out in more-than-usual numbers, as they did in California, which she won Feb. 5. In Ohio she’s benefiting from a greater number of Democratic Party regulars than in Texas, fewer college-educated or higher-income voters, and support from union households. In both states, senior citizens are crucial to Clinton’s side; independents and younger voters, to Obama’s. And he’s taken a lead over Clinton on electability, a point he may try to drive home, along with his mantle of “change,” in the days ahead."
