Cardinal Bergoglio would be my choice.

Excerpt...
Stories of his humility abound. When he was appointed a cardinal in 2001, Bergoglio persuaded hundreds of Argentines not to fly to Rome to celebrate with him but donate to the poor the money they had raised for their airline tickets.
He declined to move into the luxurious archbishop's residence, preferring a simple apartment nearby where he lives with an old bishop and usually cooks dinner.
He gets around town mostly by bus, often wearing the cassock of a simple priest rather than any episcopal finery.
In 2000, as the Pope apologised for the Church's sins down the centuries, Bergoglio had clergy wear garments of penance for sins committed during the country's military dictatorship.

John Paul II made him a cardinal together with the last group of bishops named to the honor, in February of 2001. On that occasion, Bergoglio distinguished himself by his reserve among his many more festive colleagues. Hundreds of Argentinians had begun fundraising efforts to fly to Rome to pay homage to the new man with the red hat. But Bergoglio stopped them. He ordered them to remain in Argentina and distribute the money they had raised to the poor. In Rome, he celebrated his new honor nearly alone - and with Lenten austerity.

Yet he´s not the type to compromise himself for the public. Every time he speaks, instead, he tries to shake people up and surprise them. In the middle of November, he did not give a learned homily on social justice to the people of Argentina reduced by hunger - he told them to return to the humble teachings of the Ten Commandments and the Beatitudes. "This," he explained, "is the way of Jesus." And as soon as one follows this way seriously, he understands that "to trample upon the dignity of a woman, a man, a child, an elderly person, is a grave sin that cries out to heaven," and he decides not to do it any more.
The other bishops follow in his footsteps. During the Holy Year of 2000 he asked the entire Church in Argentina to put on garments of public penance for the sins committed during the years of the dictatorship. As a result of this act of purification, the Church had the credibility to be able to ask the nation to acknowledge how its own sins had contributed to its current disaster. At the celebration of the Te Deum at the most recent national feast, last May 25th, there was a record audience for Cardinal Bergoglio´s homily. The cardinal asked the people of Argentina to do as Zacchaeus had done in the Gospel. Here was a sinister loan shark. But, taking account of his moral lowliness, he climbed up into a sycamore tree, to see Jesus and let himself be seen and converted by him.
There isn´t a politician, from the right to the extreme left, who isn´t dying for the blessing of Bergoglio. Even the women of Plaza de Mayo, ultraradicals and unbridled anti-catholics, treat him with respect. He has even made inroads with one of them in private meetings. On another occasion, he visited the deathbed of an ex-bishop, Jeronimo Podestá, who had married in defiance of the Church and was dying poor and forgotten by all. From that moment, Mrs. Podestá became one of his devoted fans.
