On behalf of the liberal groups Americans United for Change and the Constitutional Responsibility Project, PPP surveys six Senate races.
We've collected all the toplines below, along with PPP's most recent previous numbers for each race in parentheses:
AZ-Sen: Ann Kirkpatrick (D): 40, John McCain (R-inc): 42 (June: Kirkpatrick 43-41)
IA-Sen: Patty Judge (D): 39, Chuck Grassley (R-inc): 46 (June: Grassley 48-41)
NH-Sen: Maggie Hassan (D): 44, Kelly Ayotte (R-inc): 42 (June: Hassan 47-44)
OH-Sen: Ted Strickland (D): 39, Rob Portman (R-inc): 40 (June: Portman 46-42)
PA-Sen: Katie McGinty (D): 39, Pat Toomey (R-inc): 40 (June: Toomey 45-42)
WI-Sen: Russ Feingold (D): 50, Ron Johnson (R-inc): 37 (June: Feingold 51-41)
There haven’t been any clear shifts in any of these six seats in the last few weeks, which isn’t much of a surprise.
Other pollsters agree that the contests in New Hampshire and Ohio are currently very tight, while Democrats have a clear lead in Wisconsin. A recent Pennsylvania poll from Quinnipiac gave GOP Sen. Pat Toomey a strong 49-40 edge, while the Behavior Research Center recently had GOP Sen. John McCain up 40-31 in Arizona. No other groups have released numbers in months, so right now it’s just PPP’s polls against their polls. However, as we’ve noted before, both BRC and Quinnipiac kept their polls in the field for absurdly long periods of time, which can make it difficult to get an accurate reading.
As for Iowa, PPP is the only pollster that’s released horserace numbers for this contest all cycle. This poll, like their last, finds longtime Republican Sen. Chuck Grassley with a lead, but not safely ahead of ex-Lt. Gov. Patty Judge. This poll gives Grassley just a 43-40 approval rating, which would give Democrats a huge opening here; back in December, PPP gave him a strong 53-33 rating. Grassley has never won re-election with anything less than 64 percent of the vote, so it’s pretty notable if his edge is even in the high single digits.
