Horowitz said his organization had budgeted about $12,000 for the ad campaign, an amount that put advertisements in national-circulation newspapers out of his reach. Instead, he decided to send the ad to college newspapers around the country as a less expensive alternative.
After editing the liberal magazine Rampart in the late 1960s and 1970s, Horowitz became estranged from the civil rights movement, which he said focused more on portraying blacks as victims of past oppression than on pushing for equality.
In the early 1980s, he held what he called a "second thoughts" convention, inviting activist friends from the 1960s who shared his disillusionment. In the 1980s, he wrote a series of stinging biographies of the Kennedys, Fords and Rockefellers.
Once a left-winger, Horowitz is now the house conservative at Salon.com, where he writes a bi-weekly column.
