Brown is noteworthy for founding Citizens United in 1988 and for his introduction of the "Willie Horton" television ad during the 1988 presidential election campaign.

[6] In a 2007 CNN documentary, Broken Government: Campaign Killers, journalist Campbell Brown, who is not related to Floyd Brown, interviewed him briefly on the subject of the Willie Horton ad, but not about a racy ad with a toll-free number that listeners could call to hear a recording of Gennifer Flowers, a woman who had been the subject of inquiries into President Bill Clinton.

"[1] CBS Evening News reported that Brown harassed the family of Susann Coleman, a former law student of Bush's opponent Bill Clinton.

In April 1992, 30 news organizations received "an anonymous and untraceable letter" by fax "claiming Clinton had had an affair with a former law student who committed suicide 15 years ago."

Brown was contacted by David Hale, a municipal judge facing indictment for fraud, then functioning as a paid informant for the FBI.

At the same time that Brown was investigating the Clintons, he was using the tax-exempt status of Citizens United to acquire funds, urging his donors to fill out an "emergency impeachment" survey, utilizing a push-poll technique.

Brown's fundraising literature said, "Our top investigator, David Bossie, is on the inside directing the probe as Special Assistant to U.S.

"[13][14] Brown was a co-founder in 2007, with James V. Lacey, Tim Kelley, and Michael Reagan, of the National Campaign Fund in support of GOP presidential candidates Arizona Sen. John McCain and former New York City Mayor Rudy Giuliani, and in opposition to Democratic presidential candidate Hillary Clinton.

The website purports to show that the Democratic nominee has inconsistent positions regarding abortion, taxes and other issues, in addition to being soft on crime and on what the site calls "Islamo Fascism".

In the spring of 2008, working for The National Campaign Fund, Floyd Brown launched what he called "the most internet-intensive effort for an ad debut ever" to disseminate via what he claimed was three to five million emails to conservatives the implication that Barack Obama had been "soft" on crime as a state senator in Illinois before his presidential candidacy.

As some of the contributors to the "swiftboat" ads in 2004 faced stiff fines from the Federal Election Commission, Brown has refrained from operating out of 527 groups and opted for the political action committee platform and budgeting from small donors.

It operates the Reagan Ranch, also known as Rancho del Cielo, and conducts conferences, seminars, internships and disseminates educational materials nationwide.

Brown often claims publicly that the book reached "best-selling" status and sold 200,000 copies, but the New York Times determined that the sales figures were only 50,000.

[29] Brown has written extensively for many publications including the San Francisco Chronicle, the Washington Times, National Review, and Human Events.

The mission of the organization is to assist members to "create a financial legacy for their families that is shielded from excessive taxation, seizure, fraud, and inflation.

[31] On April 1, 2008, Brown appeared on Fox News Channel's Neil Cavuto business program, described only as "real estate investor," in a segment titled "New Foreclosure Bailout: Do Homeowners Really Need it?"

I think Alan Greenspan kept rates too low after the 2001 recession and that caused way too much liquidity to flow into the markets..."[32] In May 2008, Brown recommended investment in Dodge & Cox, a mutual fund that had recently offered a rare opening to new investors.
