Over the weekend, two more polls came out of the embattled Eighth Congressional District.
Republican U.S. Rep. Chip Cravaack's campaign shared the results of an internal poll that shows the freshman Republican up over Democrat Rick Nolan by 10 percentage points (50 percent to 40 percent. That poll, which included 400 likely voters, 33 percent of whom were DFL, 34 independent and 31 Republican.
Meanwhile, the Huffington Post released a Public Policy Polling poll that showed Nolan up by 4 percentage points over Cravaack (48 percent to 44 percent). That poll included 38 percent DFL, 29 percent Republican and 33 percent independent voters.
Last week, a poll completed for the Star Tribune found Nolan with a 7-percentage point lead.
The contested Eighth District is Minnesota most expensive House race by far. Already outside groups have spent about $8.6 million to fight it out.
