We have the first post-debate poll of the national presidential horserace, from Ipsos/Reuters. The top-lines are encouraging for everyone—Mitt Romney improved his lot, while President Barack Obama didn’t lose any ground. What does that look like? Like this:

Obama 48 (48)

Romney 43 (39)

That four-point jump for Romney was real and significant and takes him from “getting blown out of the water” to merely “lagging quite a bit behind.”
