He has the right to privacy of this affair. If Americans also thought eating pickles made a bad candidate, then spending money on hiding pickle eating would be justified. Why? Because, pickle eating or legal sexual relations doesn't affect a person's ability to do politics or change their stance on issues. Americans got it coming if they want to add things into politics that don't matter, like private extra-marital affairs. At this point, Americans have decided it really is a political issue, which should be allowable to handle with political funds. It's all about political strategy to hide it. Hiding legal things is unfortunately not a crime, no harm done. But, hiding illegal things should be. This sex was legal. No harm done and it's sex in American is a politically related issue. When Americans get over their sexual hang ups, then we wouldn't see this nonsense spending.
Another example of the judicial system during an economic crisis wasting effort on moral issues. We don't have the time or money to waste on this stupidity. Our energy needs to be spent on more pressing issues. When will government wake up?
