Pawlenty, Blunt, and Spitzer.
Even though listening to BRTD might not relay this, I suspect Pawlenty got a small bump of the whole bridge collapse thing. Or maybe not. Anyway, we're arguing whether his real approval presently is in the low-mid 50s or the mid-to-upper 50s. That's not a big distinction to me.
Blunt has been talked about many times on this forum. There's been a slow upward trend since the beginning of this year that may or may not be done.
Spitzer's numbers are higher than they were last month, which indicates he might have stabilized or maybe moved up slightly. His numbers are down where they are b/c of scandal (and him pissing off certain other Democrats).
Kulongoski has showed an upward trend since about election time last year. Riley has been strong throughout, I don't know what Alcon sees of importance there. I also don't see any notable movement or otherwise in the Kaine numbers to warrant much comment.
Generally, I tend to look at these polls for long-term trends most of the time, and only per each monthly installation when big events have occurred. There's not necessarily any polling logic to this, but I think it's what makes the most sense.
