That means Democrats need a bigger advantage to actually be in a position to win back the majority. In late 2006, just before they won back the House, Democrats held a 23-point advantage on Gallup's generic ballot. In late 2008, when they picked up another 25 seats, Democrats had a 15-point edge. Gallup's first test is good for Democratic fundraising and good for morale. But in terms of a real indicator, neither side is going to take a seven-point edge as a serious sign that Democrats are significantly ahead.
