MyDD is a popular left-wing political blog specializing in American politics started by Jerome Armstrong. Armstrong began the site around April 2001; it originally focused on technical and astrological analysis of financial markets, with content mainly composed of reposted comments from investor bulletin boards; * its name was short for "My Due Diligence". Around June 2001, Armstrong relaunched the site with a focus on politics. In January 2006, the name was changed to "My Direct Democracy" as part of a site redesign, with a new tagline, "Direct Democracy for People-Powered Politics". All the authors of the blog, who currently include Chris Bowers, Matt Stoller and Jonathan Singer, support the U.S. Democratic Party.
The site garnered a great deal of attention during the 2004 U.S. Presidential Election for being the first source to break the exit polls *.
MyDD was profiled in late 2005 as part of the article "Blogging Down the Money Trail" in Campaigns and Elections magazine. The article focused on the special election in Ohio's second congressional district and the ability of blogs like MyDD, Daily Kos, and Swing State Project to raise funds for Democratic candidates and draw national attention to local races. The magazine credits MyDD with being "the first major liberal blog."
Markos Moulitsas ZĂșniga, founder of the most-visited political blog in the world, Daily Kos, began commenting on MyDD before starting his own blog in May of 2002, and refers to MyDD as his "blogfather".
