Based on George Bush's net approval rating of −1% in the final Gallup Poll in June, a 3.7% growth rate for real GDP during the first two quarters of 2004, and the fact that the Republican Party had controlled the White House for only one term, the time-for-change model predicted that Mr. Bush would win reelection with 53.7% of the major party vote. This forecast was made in late July, before the Republican National Convention and more than three months before Election Day.
