No bounce yet for Obama, but he's still leading in New Jersey. Here's our guide to today's polls and why they matter. 

Findings: In a rolling poll Romney still holds a one-point lead among likely voters — 45 percent to 44 percent — over Obama. 
Pollster: Reuters/Ipsos 
Methodology: Online interviews with 1,623 registered voters September 2 through 6 with a "credibility interval" of +/-2.8 percentage points. 
Why it matters: According to Reuters the poll indicates that Obama "has not received much of a bounce yet in popular support from the Democratic National Convention." The same poll last week indicated a "small bounce" for Romney from the RNC. 
Caveat: Julia Clark from Ipsos told us that while the data does include small percentage of people polled today, "I don't think we can consider today's numbers a referendum on Clinton's speech," she said, adding that bounces can lag behind the convention in their rolling polls. So far, though Democrats have said they aren't expecting the race to shift. 

Findings: In New Jersey Obama leads by seven points among likely voters: 51 percent to 44 percent. 
Pollster: Quinnipiac 
Methodology: Telephone interviews with 1,471 likely voters August 27 through September 2 with a margin of error of +/-2.6 percentage points. 
Why it matters: We've mentioned before that even New Jersey Governor Chris Christie, a Republican, doesn't think his party's candidate has much of a hope in the state. That said, this poll shows a tighter race than a different poll of likely taken before the Republican national convention which gave Obama a 14 point lead. 
Caveat: This poll was taken entirely before the beginning of the DNC.
