California Assembly Speaker Jesse M. Unruh once famously said of moneyed political interests: “If you can't take their money, drink their booze, eat their food, screw their women, and vote against them, you don't belong here.” In other words, giving cash to politicians is no guarantee they’ll carry your water. But campaign contributions to elected officials don’t hurt either. The links between money and votes is an endlessly debated subject in official Washington. Cynics say campaign cash often buys support. Others claim that examining who opened their wallets most for a politician is simply an indication of who those backers think best advocates their agenda. Either way, though, following the money is often illuminating.
