Gallup has announced that in their tracker Mitt Romney has pulled dead even with Obama since the debate:
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.
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%.
