Another Tuesday in September brought another polling dump by the Democratic Congressional Campaign Committee.

A DCCC release Tuesday morning touted recent polling that showed the party in good standing in eight competitive Democratic-held districts. The release comes a week after the DCCC pushed out a dozen polls that also showed good news for Democratic incumbents around the country. The recent emphasis on polling appears to be part of a concerted effort to push back against the idea that the prospects for House Democrats have grown increasingly gloomy heading into the final stretch before Election Day.

Over the past couple months, the DCCC was criticized for not releasing its poll numbers while Republicans dribbled out a steady stream of favorable survey data.

Tuesday’s release included DCCC internal polling and polls conducted by Democratic campaigns. The DCCC also included outside group polling information. The release included polling from districts that have long been considered battleground targets, such as Nevada’s 3rd, as well as less high-profile races, such as Oklahoma’s 2nd, which, despite it’s strong conservative leanings, hasn’t been considered in play so far this cycle.

Here’s a rundown of the polls that were included in Tuesday’s release:

• A Grove Insight poll conducted Sept. 7-9 showed Rep. Mark Critz (D) ahead of Republican Tim Burns 48 percent to 41 percent in Pennsylvania’s 12th district. The survey of 400 likely voters was paid for by the DCCC and had a 4.9-point margin of error.

• An Anzalone Liszt Research poll conducted Sept. 7-9 showed Rep. Harry Teague (D) ahead of former Rep. Steve Pearce (R) 51 percent to 44 percent in New Mexico’s 2nd district. The survey of 400 likely voters was paid for by the DCCC and had a 4.9-point margin of error.

• A Grove Insight poll conducted Sept. 7-9 showed Rep. Ben Chandler (D) ahead of Republican Andy Barr 52 percent to 38 percent in Kentucky’s 6th district. The survey of 400 likely voters was paid for by the DCCC and had a 4.9-point margin of error.

• A Grove Insight poll conducted Sept. 7-9 showed Rep. Kurt Schrader (D) ahead of Republican Scott Bruun 42 percent to 29 percent in Oregon’s 5th district. The survey of 400 likely voters was paid for by the DCCC and had a 4.9-point margin of error.

• A Bennett, Petts & Nomington poll conducted Sept. 7-8 showed Rep Betsy Markey (D) tied with Republican Cory Gardner at 38 percent and Independent Ken Waszkiewicz at 5 percent in Colorado’s 4th district. The Congresswoman’s internal campaign poll of 400 likely voters had a 5-point margin of error.

• A Myers Research & Strategic Services survey conducted Sept. 7-8 showed Rep. Dan Boren (D) ahead of Republican Charles Thompson 65 percent to 31 percent in Oklahoma’s 2nd district. The Congressman’s internal poll surveyed 400 likely voters and had a 4.9-point margin of error.

• A Voter/Consumer Research survey conducted Aug. 31-Sept. 3 showed Rep. Leonard Boswell ahead of Republican Brad Zaun 48 percent to 39 percent in Iowa’s 3rd district. The poll of 300 voters was conducted for the conservative American Future Fund and had a 3.6-point margin of error.

• A Mason-Dixon Polling & Research survey conducted Sept. 7-9 showed Rep. Dina Titus (D) leading Republican Joe Heck 47 percent to 43 percent in Nevada’s 3rd district. The poll of 400 likely voters was conducted for the Las Vegas Review-Journal and had a 5-point margin of error.

The release comes as DCCC Chairman Chris Van Hollen (Md.) works to keep his colleagues optimistic heading into November and fire up a Democratic electorate that he admitted Monday is not as enthusiastic as Republican voters.

“It’s pretty clear that over the summer there was this political energy deficit, and our challenge is to close the gap, and I think we’re doing it,” Van Hollen said in an interview Monday. The chairman said he was encouraged that Democrats are finally recognizing what’s at stake in November, and that is helping to close the enthusiasm gap.
