@Irishk,
LARRY SABATO (Sept 2nd)-
The UVA pundit is out with his pre-Labor Day commentary. His prognosis for the Democrat's is now much more dire with 60 days to go until the general election.
SENATE: For several months he had been showing the Repubs picking up 7 seats. He now says 8 or perhaps 9. And there is an outside chance of the number hitting 10, which would leave the Repub's with a 51-49 majority.
He has moved CO and PA (now D states) from Tossup to Lean Repub and OH (R) from Tossup to Leans Repub.
He has added WA and WI (D) to the Tossup category, joining FL (open), CA, IL and NV (D).
HOUSE: A week or so ago, he projected the Repubs picking up 32 seats net. That would still give the Dems a majority (225-210). Today he believes the Repubs could perhaps pick up 47 which would give them the majority (225-210).
In his narrative, Sabato talks about how he gets to projections. "(The) estimate is based on careful district by district analysis, plus electoral monitoring based on trends in President Obama's Gallup job approval ratings and the Democrat-versus-Republican congressional generic ballot."
Mid-term elections tend to favor the party not in power and 2010 was certainly shaping up along those lines. If the economy had shown signs of recovery, the Dems might have been correct in assuming that the losses could be held to manageable levels.
Clearly the economy remains bogged down and it is likely there will not be any signs of improvement in the next two months.
Sabato also notes that in 2006 and 2008 the Dems picked up a total of some 50 House seats. A number of those were won in Repub territory, often by slim margins (eg my district- VA5 - went Dem for the 1st time forever, by a mere 600 votes). Those seats are highly exposed to a GOP wave.
