Registered voters' preferences for president are evenly split in the first three days of Gallup tracking since last Wednesday's presidential debate. In the three days prior to the debate, Barack Obama had a five-percentage-point edge among registered voters.
Gallup typically reports voter presidential preferences in seven-day rolling averages; the latest such average as of Saturday interviewing shows Obama with an average three-point edge, 49% to 46%, among registered voters. This Sept. 30-Oct. 6 field period includes three days before the Oct. 3 debate, the night of the debate itself, and three days after the debate.
Even on this basis, the race has become somewhat more competitive compared with before the first debate. Obama held four- to six-point leads in Gallup's seven-day tracking results in the eight days prior to the Oct. 3 debate.
An Oct. 4-5 Gallup poll finds roughly two in three Americans reporting that they watched the Oct. 3 debate, similar to what Gallup measured for each of the three 2008 presidential debates. Those who viewed the debate overwhelmingly believe Romney did a better job than Obama, 72% to 20%. Republicans were nearly unanimous in judging Romney the winner. But even Democrats rated Romney as doing a better job than Obama, 49% to 39%.
Gallup has assessed opinion on who did better in most past presidential debates; some of these polls were conducted the night of the debate with pre-recruited samples of debate watchers immediately after it concluded, and some were conducted with more general samples of Americans in the days that followed the debate. Across all of the various debate-reaction polls Gallup has conducted, Romney's 52-point win is the largest Gallup has measured. The prior largest margin was 42 points for Bill Clinton over George H.W. Bush in the 1992 town hall debate.Mark Blumenthal writes at The Huffington Post:
Most of the polls conducted by other organizations since Wednesday's debate have shown a similar shift in Romney's direction. The HuffPost Pollster tracking model, which combines national and statewide survey data, currently gives Obama just a one and a half percentage point edge nationwide (47.6 percent to 46.0 percent as of this hour, although the estimate will update as new polls become available).
