The constitutional requirements for holding congressional office in the United States are few and simple. They include age (twenty-five years of age for the House of Representatives, Thirty for the Senate); citizenship (seven years for the House, nine years for the Senate); and residency in the state from which the officeholder is elected. Thus, the constitutional gateways to congressional office holding are fairly wide.
　
Even these minimal requirements, however, sometimes arouse controversy. During the 1960’s and 1970’s, when people of the post-Second War "baby boom" reached maturity and the Twenty-sixth Amendment (permitting eighteen year olds to vote) was ratified, unsuccessful efforts were made to lower the eligible age for senators and representatives.
　
Because of Americas’ geographic mobility, residency sometimes is an issue. Voters normally prefer candidates with long-standing ties to their states of districts. In his 1978 reelection campaign, for instance, Texas Senator John Tower effectively accused his opponent, Representative Robert Krueger, of having spent most of his life "overseas or in the East" studying or teaching -- a charge taken seriously in Texas. Well-known candidates sometimes succeed without such ties. New York voters elected to the Senate Robert F. Kennedy (1965-1968) and Daniel Patrick Moynihan (1977) even though each had spent much of his life elsewhere. While members of the House of Representatives are not bound to live in the district from which they are elected, most do so prior to their election.
　
In the seat, the "one person, one vote" rule does not apply. Article I of the Constitution assures each state, regardless of population, two Senate seats, and Article V guarantees that this equal representation cannot be taken away without the state’s consent. The founders stipulated that senators be designed by their respective state legislatures rather than by the voters themselves. Thus, the Senate was designed to add stability, wisdom, and forbearance to the action of the popularly elected House. This distinction between the two houses was eroded by the Seventeenth Amendment (1913), which provided for the direct population election of senators.

The sooner had the first intrepid male aviator safely returned to Earth, it seemed that women, too, were smitten by an urge to fly. From mere spectators they became willing passengers and finally pilots in their own right, plotting their skills and daring line against the hazards of the air and the skepticism of their male counterparts. In doing so, they enlarged the traditional bounds of a women’s world, won for their sex a new sense of competence and achievement, and contributed handsomely to the progress of aviation.
　
But recognition of their abilities did not come easily. "Men do not believe us capable." the famed aviator Amelia Earhart once remarked to friend "Because we are women, seldom are we trusted to do an efficient job." Indeed old attitudes died hard: when Charles Lindbergh visited the Soviet Union in 1938 with his wife, Anne -- herself a pilot and gifted proponent of aviation -- was astonished to discover both men and women flying in the Soviet Air Force.
　
Such conventional wisdom made it difficult for women to raise money for the up-to-date equipment they needed to compete on an equal basis with men. Yet compete they did, and often they triumphed dandily despite the odds.
　
Ruth Law, whose 590-mile flight from Chicago to Hornell, New York, set a new nonstop distance record in 1918, exemplified the resourcefulness and grit demanded of any woman who wanted to fly. And when she addressed the Aero club of America after completing her historic journey, her plainspoken words testified to a universal human motivation that was unaffected by gender: "My flight was done with no expectation of reward," she declared, "just for the love of accomplishment."
