Media Matters founder David Brock makes statements that should put his tax exempt status in danger

To be tax exempt, one can't engage in direct political activity. Yet, David Brock sees Media Matters' goal as reforming the Democratic party. He also sees it as involved in Democrat party fundraising. These seem like unabashedly direct political activities. From Doug Schoen:

Brock was compelling in arguing that he would like to see the Democratic Party develop a different, more inclusive message for the 2012 election, recognizing that the Party in large part, had failed in 2010 because they did not present a positive and affirmative case to the electorate-- an argument that I could only agree with.

Brock also made clear that he saw his mission to try to the best of his ability to counteract Republican fundraising efforts, that had frankly exceeded in substance and sophistication, those of the Democrats. . . .

Brock also made it clear to me that his focus was on the party, and providing and creating a level playing field for it and its advocates, rather than positioning himself as exclusively or even primarily as a media critic. . . .
