VOANews.com: "Less than half of those surveyed, 47 percent, say the United States did the right thing by taking military action in Iraq. That number is down from 58 percent in March and 63 percent back in December.
The poll by The New York Times and CBS News measures Mr. Bush's approval rating at 46 percent, down five percent from the same poll in March and down more than 20 percent from a year ago.
The drop comes after a month of attacks and clashes in Iraq that have killed at least 125 U.S. military personnel.
Like other polls, the new survey shows a close race between Mr. Bush and his main challenger in the November election, Democrat John Kerry.
Asked who they would vote for if the election were held today, 46 percent of registered voters said they would vote for Mr. Kerry, 44 percent for Mr. Bush.
When independent candidate Ralph Nader was factored into the race, Mr. Bush came out slightly ahead"
