http://www.usaelectionpolls.com/ - I like this site, they compile their data from all the various political polls out there. Survey USA use to be like that but changes format and now I can't find shit.
Democrat Pickups:
It seems where there is an open seat there is a good chance we could be picking up another democrat in the senate (ok so not Idaho, I'll survive). With the retirement of Allard, Domenici and John Warner we are looking very strong to put democrats in their place with the Udalls (CO and NM) and Mark Warner in Virginia.
It also seems to be a good year for revenge up in New Hampshire. Six years ago there were investigations about the phone lines being jammed that prevent voters for getting help for finding their local polls. This and a lackluster 6 years from Sununu is making former very popular governor Jean Shaheen sitting pretty in her 2nd run against Sununu.
Finally are practically at a dead heat with Alaska and Mississippi. Let's face it, Ted Steven's popularity is starting to wear a bit thin in Alaska and perhaps some fresh blood like Mark Begich might be the answer.
And who said Mississippi is a surefire win for republicans when you have popular govenor Ronnie Musgrove running on the democratic ticket for the seat left open by Trent Lott.
