Okay I'll be fair and say you're miming something a lot of websites do post. It's a BS comparison by itself. Polls without the larger narrative can be BS. Polls without explanation can be BS. Polls are also a one time snapshot. There can be outlier polls. The poll you are looking at I believe came from CNN since they posted an article about it. If you know of a Pew or Gallup poll that reiterates that then feel free to post it. Obama's popularity is not low. I think Obama's lowest poll points were maybe around 43% approval? That's not a great number but it was a one time low point. Bush sank to the mid 20's at one point. That's unbelievably low. So when you look at the broader history of both men's presidencies, their electoral results, and you factor in the softening of public images post presidency and you can understand why it's silly to paint with a broad brush that Obama is less popular than Bush.
