It could be just a noise, as it seems right now.
Obama 52/46 right now.
Too much hype. Obama has consistently been at low-50s on Gallup's weekly average, with occasional high numbers in other polls. If he was truly nearing Bill/Eisenhower-level popularity, his numbers would be trending to upper-50s with a base of no lower than 55%.
In the end, I think Obama will go out well-liked and be more liked over time, but as much as I like & respect the guy, it's clear this election has brought to light a better appreciation for him, whereas people like Eisenhower were almost
always popular, even
(moderately, anyhow) during a recession that otherwise caused the rest of the GOP to implode downballot.
