(CNN) - National Democrats are out with a new strategy to gin up enthusiasm among members of the base and line their campaign coffers, warning supporters that the party is likely to be significantly outspent by Republican groups this election cycle.
The memo – sent to Democratic activists and fundraisers around the country – says Republican-supporting groups are likely to spend more than $300 million leading up to the midterm elections – a total, Democrats say, that dwarfs previous midterm election spending.
The memo identifies 14 organizations estimated to spend $500,000 or more this election cycle. Topping the list is the U.S. Chamber of Commerce, which Democrats say aims to spend $75 million this year. Also on the list is the Karl Rove-backed American Crossroads, which Democrats warn will spend $52 million. Other groups on the list include the fiscally conservative Club for Growth and FreedomWorks - the group led by former House Majority Leader Dick Armey that has offered organizational support to the Tea Party movement.
Of course, Democrats are not without their own powerful third-party organizations, including a string of unions that have already spent heavily. The Democratic committees have also either kept pace or surpassed the fundraising efforts of their Republican counterparts this year. But in a year that appears ominous for the incumbent party, Democrats may be wary of getting caught with empty pockets come the fall.
