"Funding sources
Media Matters initially received "more than $2 million in donations from wealthy liberals" with ties to the Democratic party (including Peter Lewis of Progressive Insurance, Steve Bing, Marcy Carsey, Susie Tompkins Buell, Leo Hindrey, Gail Furman, and James Hormel) and "was developed with help from the newly formed Center for American Progress".[23][24][25] It also has received significant funding from Democracy Alliance (funded in large measure by George Soros), MoveOn.org, and the New Democrat Network.[25][26]"

As for myself, unless there is a reputable source of this, I shall consider this propaganda.
