An item from L.M. Boyd's "Grab Bag" newspaper column submitted by a nurse: "People who don't relate well to other people are the ones with high blood pressure. I'm sure of it. No, I have no documented data. But as a lifelong nurse, I've taken countless blood pressure readings. The loners run high."

During the primary campaign in 1992, Bill Clinton appeared on “60 Minutes” with Hillary Rodham Clinton, to answer questions about his rumored marital infidelity. When asked specifically if he had had a twelve-year affair with Gennifer Flowers, he said their relationship was “very limited, but until this, you know, friendly, but limited.” In another interview where Clinton was asked if he denied having an affair with Flowers, he said: “I’ve said that before and so has she.”

Bill Clinton’s proposal to curb cigarette advertising was a bad idea. Whether to smoke or not is a personal decision, one the government shouldn’t interfere in. Besides, Clinton’s record--from his failure at reforming health insurance to his appointment for Surgeon General--was poor.

Senator Trueheart is asked in a press conference whether he supports the American military presence in Afghanistan. The senator replies: “I think it’s important to defend democratic principles.

One critic of the Clinton administration wrote in an editorial highly critical of Clinton’s first two years in office, “That Mr. Clinton’s reign as a national leader was to be a disastrous one was, after all, clear very early--well before he took office.” (Dorothy Rabinowitz, “Requiem for the Clinton Presidency,” The Wall Street Journal, February 6, 1995.)

In May 1996, it was revealed that a clothing line using Kathie Lee Gifford’s name was being manufactured by women in Central American sweatshops toiling in appalling conditions and for very little pay (at least by American standards). Gifford pledged to pressure companies to take their business away from manufacturers who exploit Third World workers. One often-heard argument against Gifford’s position went like this: The impact of Kathie Lee’s crusade will drive businesses from Central America, eliminating jobs and making living conditions for the poor even more miserable. Sweatshops are better than no shops at all.

From an essay by Susan Faludi titled “Blame It on Feminism” in her book, Backlash: “Law enforcement officials and judges, too, have pointed a damning finger at feminism, claiming that they can chart a path from rising female independence to rising female pathology. As a California sheriff explained it to the press, ‘Women are enjoying a lot more freedom now, and as a result, they are committing more crimes.’”

The President of XYZ Corporation states: “The recent settlement between management and the labor union was a huge mistake. Giving in to the union’s demands for a wage increase has resulted in the lowest production figures in almost a decade!”
