The Republican megadonor and his wife, Miriam, are gearing up for the midterm elections, kicking in $55 million to help their party keep control of Congress in November. Outside of his political contributions, Adelson has donated more than $1.1 billion to charity in his lifetime, mostly to Jewish organizations. In April he announced another $70 million donation to Birthright Israel Foundation, which funds trips to Israel for young Jewish people, bringing his total giving to the group to $410 million. Adelson, who is CEO and majority owner of Las Vegas Sands, one of the largest casino companies in the country, made his first foray into gambling at age 55 when he bought the Sands Hotel & Casino on the Las Vegas Strip.
