PRINCETON, NJ -- Barack Obama and Hillary Clinton remain in a statistical tie in the preferences of national Democratic voters, with Obama at 47% support and Clinton at 46%.
Today's results are based on interviews conducted March 22 and March 24-25, with no interviews conducted Easter Sunday, March 23.
After the changes that occurred over the last two weeks spanning the Rev. Jeremiah Wright controversy, the Democratic race appears to have settled down, at least for the time being. Clinton's share of Democratic preferences has been either 45% or 46% for the last four Gallup Poll Daily tracking reports, while Obama's share has been either 47% or 48%.

Voters' preferences in two hypothetical November general election matchups are also very stable. In separate trial heats for president, John McCain has a two percentage point lead over both Obama and Clinton. -- Frank Newport
