MITT ROMNEY, THE MAN, WALKING HIS TALK
Besides his great business and governing career, he has other ways he has proven himself, not through rhetoric, but through action.
He was requested to rescue the scandal ridden 2002 Olympics, which he stepped forward and did, contributing his time for the good of others. A brief video coverage. The Olympics Turnaround.
Generous in his giving, "he has been generous to many community, civic and political advocacy organizations" per The Huffington Post article. ""They want to give back to others who have not had the opportunities they had," she said. "For someone in a political role, the mission of creating responsible citizens and leaders, I think, would resonate with someone in a leadership role in business or politics."
