Presidential and congressional campaigns are frustrating times. So much of what is said is misleading. It is easy to see why political advisers are so adept at moving from one campaign to another without skipping a beat or dwelling on any implied discrepancy in their own pattern of support. One can always find a multitude of sins on all sides and in almost all campaigns. It's easier to criticize than come up with constructive solutions, and at campaign time the opportunities are in spades. It's not surprising that campaigns quickly turn negative.
