http://en.wikipedia.org/wiki/United_States_Senate#QualificationsArticle I, Section 3 of the Constitution sets three qualifications for senators: 1) each senator must be at least 30 years old, 2) must have been a citizen of the United States for at least the past nine years, and 3) must be (at the time of the election) an inhabitant of the state they seek to represent. The age and citizenship qualifications for senators are more stringent than those for representatives. In Federalist No. 62, James Madison justified this arrangement by arguing that the "senatorial trust" called for a "greater extent of information and stability of character."
The Senate (not the judiciary) is the sole judge of a Senator's qualifications. During its early years, however, the Senate did not closely scrutinize the qualifications of members. As a result, three Senators that were constitutionally disqualified due to age were admitted to the Senate: Henry Clay (aged 29 in 1806), and Armistead Thomson Mason (aged 28 in 1816) and John Eaton (aged 28 in 1818). Such an occurrence, however, has not been repeated since.<15> In 1934, Rush D. Holt, Sr. was elected to the Senate at the age of 29; he waited until he turned 30 to take the oath of office. Likewise, Joe Biden was elected to the Senate shortly before his 30th birthday in 1972; he had passed his 30th birthday by the time the Senate conducted its swearing-in ceremony for that year's electees in January 1973.
The Fourteenth Amendment to the United States Constitution disqualifies from the Senate any federal or state officer who had taken the requisite oath to support the Constitution, but later engaged in rebellion or aids the enemies of the United States. This provision, which came into force soon after the end of the Civil War, was intended to prevent those who sided with the Confederacy from serving. That Amendment, however, also provides a method to remove that disqualification: a two-thirds vote of both chambers of Congress.

So tell me - what part of these qualifications does Caroline Kennedy NOT meet?
