WASHINGTON – The Democrats’ plan to hold onto their narrow Senate majority goes by the name “Bannock Street project.” It runs through 10 states, includes a $60 million investment and requires more than 4,000 paid staff members. And the effort will need all of that – and perhaps more – to achieve its goal, which is nothing short of changing the character of the electorate in a midterm cycle.

The Democratic Senatorial Campaign Committee is preparing its largest and most data-driven ground game yet, relying on an aggressive combination of voter registration, getting out of the vote and persuasion.

The committee hopes to make the 2014 midterm election more closely resemble a presidential election, when more traditional Democratic constituencies – single women, minorities and young voters – turn out to vote in higher numbers, said Guy Cecil, the committee’s executive director.

“Bannock Street” is drawn from the name of the Denver field headquarters for the campaign of Sen. Michael Bennet, D-Colo., for whom Cecil was the chief of staff. Bennet won in 2010 in part by generating higher-than-forecast turnout.

“We’re making a fundamentally different choice” on campaign strategy, Cecil said. “Yes, we have to be on TV, and yes we have to help close the gap between Democrats and Republicans on the air, but we’re not willing to sacrifice the turnout operation or the field operation to do that.”

Matt Lira, deputy executive director at the National Republican Senatorial Committee, said on the Republican side, there was a “holistic obsession” to use existing data and technology to not simply “reverse engineer” the most recent Obama campaign.

“If all we achieve is catching up to Obama 2012, we’ll be two years behind, so we want to focus on what does the technology enable us to do in 2014,” he said.

The Bannock Street project is focused on 10 states/commonwealths – Alaska, Arkansas, Georgia, Iowa, Kentucky, Louisiana, North Carolina, Michigan, Montana and West Virginia – with plans for senior field operatives and other staff members to be in place by the end of the month.

The state teams will each be required to come up with a “strategic plan,” complete with a budget and data-mapping program.

The committee is also joining with Civis Analytics, a data firm founded by Dan Wagner, who served as the chief analytics officer on Obama’s 2012 campaign. The partnership will provide Senate Democrats with additional data.
