I am correct that the goal of this site is to support the Democratic party?

9. The Mission Statement...

From: https://www.democraticunderground.com/?com=aboutus

Democratic Underground is an online community where politically liberal people can do their part to effect political and social change by:

Interacting with friendly, like-minded people;
Sharing news and information, free from the corporate media filter;
Participating in lively, thought-provoking discussions;
Helping elect more Democrats to political office at all levels of American government; and
Having fun!

After more than a decade online, Democratic Underground still hosts the most active liberal discussion board on the Internet. We are an independent website funded by member subscriptions and advertising, and we have no affiliation with the Democratic Party. Democratic Underground is a truly grassroots community where regular members drive the discussion and set the standards. There is no other website quite like it anywhere on the Internet.

We are always looking for friendly, liberal people who appreciate good discussions and who understand the importance of electing more Democrats to office.
