Ok, for Ron....
The important thing about Andrew Breitbart Ron, is that Mike and Denise know who he is. You feel his influence on these pages all the time;
Main article: Anthony Weiner sexting scandal
On May 28, 2011, Breitbart posted a sexually explicit photo on his BigJournalism website of New York Representative Anthony Weiner obtained through Weiner's Twitter account. Initially Weiner denied that he had sent a link to the photograph to a 21-year-old female college student, but after questions developed, he admitted to inappropriate online relationships. On June 6, 2011 Breitbart reported other photos Weiner had sent, including one that was sexually graphic. On June 8, 2011, the sexually graphic photo was leaked after Breitbart participated in a radio interview with hosts Opie and Anthony, though Breitbart stated that the photo was published without his permission. Weiner subsequently resigned from his congressional seat on June 21, 2011.
Main article: Resignation of Shirley Sherrod
On July 19, 2010, Breitbart posted two short videos showing excerpts of a speech by Shirley Sherrod at an NAACP fundraising dinner in March 2010. The videos ensuing controversy resulted in Sherrod being fired from the United States Department of Agriculture on July 19. After Breitbart was criticized for taking Sherrod's words out of context, he posted the complete 40-minute video of the speech. The NAACP stated that the video excerpts aired by Breitbart were deliberately deceptive and said that he had "snookered" the group. Secretary of Agriculture Tom Vilsack later apologized to Sherrod and offered her a new job. In 2011, Sherrod brought suit against Breitbart for defamation.
ACORN undercover videos
Main article: ACORN 2009 undercover videos controversy
Breitbart was also involved in the 2009 ACORN video controversy. Hannah Giles posed as a prostitute seeking assistance while James O'Keefe portrayed her boyfriend, and clandestinely videotaped meetings with ACORN staff. Subsequent criminal investigations by the Brooklyn District Attorney's office and the California Attorney General found the videos were heavily edited in an attempt to make ACORN's responses "appear more sinister", and contributed to the group's demise. Breitbart then provided a forum for O'Keefe on his BigGovernment.com website and defended his actions on Sean Hannity's Fox News Channel program.
Breitbart has also been embroiled in a controversy within the conservative movement related to the participation of gay group GOProud in the Conservative Political Action Conference (CPAC), an annual conference held in Washington, D.C. by the American Conservative Union. In 2011 he was the primary host of a party that served to "welcome" the "homocons" to the convention (though it was the second year they had been participants). This flew in the face of a boycott staged by a few social conservative groups that were offended by the inclusion of GOProud within the conservative fold. Writer, producer, and publisher Roger L. Simon referred to the group as a "game-changer" for the Republican party, and asserted that it represented a turning point in the appeal that the conservative movement might hold for young people. Breitbart is now on the Advisory Board of GOProud. http://en.wikipedia.org/wiki/Andrew_Breitbart
More important than who he is though - or that Mike and Denise know who he is, is the reaction the subject comments elicit from his audience, indicating their own private fantasy to do bodily harm to liberals. You would do yourself a favor to review the source material and watch the video.
The crowd reaction is a complement to the thunderous applause Ric Perry received at the MSNBC Republican primary debate, the only real crowd outburst, for having executed hundreds of prisoners in Texas. And, it goes right along side the crowd at the CNN debate that cheered 'yes' to Blitzer's hypothetical man with no insurance in a sudden coma when he asked Ron Paul if he should merely be allowed to die.
