Since Gallup refuses to headline this story like the one they did Monday, I thought I'd help them out.
Although Gallup's main focus is on seven-day rolling averages, a breakdown of interviewing over shorter periods can be helpful in understanding the short-term impact of events like conventions and debates. As Gallup reported Monday, Romney gained ground among registered voters in the immediate aftermath of his Oct. 3 debate, moving from a five-point deficit prior to the debate to a tie in the immediate three days that followed. Most of that gain was driven by substantial Romney leads in the Thursday and Friday tracking.
Since Saturday, however, Obama has regained a 50% to 45% edge among registered voters in interviewing conducted Sunday and Monday -- the same as his margin in the three days prior to the debate. Although these two days of interviewing involve relatively small sample sizes, they suggest that Romney's debate "bounce" may be fading.
