A week after Election Day, three Republican governors mentioned as 2016 presidential candidates — Bobby Jindal, John Kasich and Bob McDonnell — each stopped by the Venetian Resort Hotel Casino to meet privately with its owner Sheldon Adelson, a man who could single-handedly underwrite their White House ambitions.

Planning a presidential campaign used to mean having coffee with county party chairs in their Iowa or New Hampshire living rooms. The courting of Adelson, a full four years out from 2016, demonstrates how super PAC sugar daddies have become the new must-have feature for White House wannabes.
