Some of the most emotionally powerful words are undefined, such as "social justice," "a living wage," "price gouging" or a "fragile" environment, for example. Such terms are especially valuable to politicians during an election year, for these terms can attract the votes of people who mean very different-- and even mutually contradictory-- things when they use these words.
It may not be possible to have machines call balls and strikes in baseball, since the vertical strike zone depends on the height of each batter. But a machine can tell whether any part of the ball passed over any part of the plate, so that umpires won't be able to call their own "wide strikes" any more.
It is hard to get the supporters of Barack Obama to give a coherent reason for their support. The basis for their support seems to be guilt, gullibility or-- in the case of some conservatives-- a hatred of John McCain.
It is heart-warming to see the Williams sisters maturing as people. They made tennis history from the beginning but they had a lot to learn about human relations-- and now they seem to have learned it.

Although most of the mainstream media are still swooning over Barack Obama, a few critics are calling the things he advocates "naive." But that assumes that he is trying to solve the country's problems. If he is trying to solve his own problem of getting elected, then he is telling the voters just what they want to hear. That is not naive but shrewd and cynical.
