AMERICANS SEEM TO like graphs. We want to know who's bar is the longest on the histogram or who has the largest slice of the pie chart. Some people are critical of this "horse race" approach to campaign coverage, but almost every major news outlet and political research group conducts polls.

Polls may not always accurately predict the outcome of a race, but they are important to a candidate striving to look like he's "the best."
