In March 2006, co-founder Domenech was hired as a blogger by the Washington Post Online, but was criticised for alleged plagiarism in some of his prior writings during college.

On July 12, 2008, RedState launched a new version of its site, called RS3, introducing new features such as the ability to organize contributor and user diaries by state; action centers allowing users to take action related to emerging political issues; links to share posts via other networking sites such as Facebook, Digg, and MySpace; and easier searching between related content on the Internet.
On August 13, 2011, Texas Governor Rick Perry announced his candidacy for President of the United States at RedState's 2011 RedState Gathering. The Austin American-Statesman reported that this was due to the growing influence of the site and Erickson.
