Barack Obama and Hillary Clinton are in a statistical dead heat in Indiana, one of two states that hold the next primaries on May 6, according to a Research 2000 poll conducted April 21-24. In North Carolina, the other May 6 state, polls have consistently shown Obama with a lead. The Indiana poll has Obama at 48 percent and Clinton at 47 percent with 2 percent undecided. The margin of error is 4 points.

A second poll, this one for the Indianapolis Star-WTHR-TV, also showed the race to be a toss-up with Obama leading 41 percent to 38 percent, within the survey’s 4.2 percent margin of error. The poll was conducted April 20-23. But this poll showed a much higher number of undecided voters – 21 percent.

And a third – American Research Group – has Clinton ahead of Obama 50 percent to 45 percent with 3 percent undecided. The margin of error is 4 percent and the poll was conducted April 23-24.
