One of the defining elements of the 2012 presidential campaign is money. Not that the candidates themselves have raised all that much; except for President Obama, they haven't. But two dozen wealthy Americans have put in at least $1 million each.
Mostly, they're a mix of Wall Street financiers and entrepreneurs. One of the biggest donors is Sheldon Adelson, a casino magnate who is worth about $25 billion.
Since January, he has put more than $10 million into the superPAC backing Newt Gingrich. And that money has kept Gingrich's presidential hopes alive when the candidate's own campaign was out of cash.
Why is Adelson doing this? He sees Gingrich as the guy who can get what Adelson wants for Israel. For Adelson, Israel is a personal cause.
