(CNN) - As liberals flock to Detroit this week for a major progressive confab, a leading grassroots group announced a big fundraising haul to help Democratic candidates ahead of the midterm elections.
The Progressive Change Campaign Committee said Wednesday that it raised over $1 million this campaign cycle. The report comes a day before the kickoff of Netroots Nation, the largest annual gathering of progressives in the country.
The group, which is a major backer of Sen. Elizabeth Warren of Massachusetts, will have a significant presence at the four-day liberal gathering surrounding the Massachusetts senator and liberal icon's keynote address.
"Elizabeth Warren's economic populist agenda is popular from Maine to Iowa to Oregon and progressives are working to elect Elizabeth Warren's allies in 2014," said Adam Green, the group's co-founder.
"This grassroots outpouring shows that the path to winning elections - and keeping the Senate - is to campaign on an economic populist agenda including Wall Street reform, expanding Social Security benefits, and reducing student debt."
The PCCC said it raised over $2.7 million for candidates in 2012, but added that their most recent fundraising success indicates a solid and growing progressive infrastructure.
Warren has a large cadre of support among progressives urging her to launch a campaign, though she's adamantly said she isn't running for the White House.
Still, she's had a frequent presence on the campaign trail, stumping in nearly half a dozen states so far this year for other candidates ahead of the 2014 midterms.
But 2016 is all in full-swing as other possible Democratic contenders court the gathering of progressives, who are a key part of the Democratic Party's base.
A tough critic of Wall Street and big banks, the first-term senator's staple as a politician has been advocating for consumers against unfair practices in the banking industry.
Vice President Joe Biden, also a possible 2016 contender, will address the liberal gathering.
The presumed frontrunner for the Democratic nomination, Hillary Clinton, will not attend the conference but several Clinton supporting groups will be there.
