I have never seen or heard of a single poll that Romney is winning. I haven't seen or heard anyone projecting Romeny to win. That is not the feeling here in the US. I'm talking about all over the US. Romeny is the underdog coming into this thing. I have no idea where you are getting this information but Obama is the clear front runner even today.
Gallup isn't exactly obscure...
Gallup editor-in-chief Frank Newport tells Bloomberg Businessweek that the release of Monday’s tracking poll, set for 1 p.m., will show Mitt Romney leading President Obama 49 percent to 48 percent among likely voters nationally. This is the first tracking poll released since Hurricane Sandy and is notable for the strong movement to Obama. The last Gallup poll on Oct. 29 showed Romney up by 5 points—51 percent to 46 percent. Romney’s one-point lead is within the margin of error and, statistically speaking, amounts to a tie. “It’s tied today at 1 o’clock,” Newport said by phone Monday morning.
