Hope for the world. Or not.

At first I thought there was hope for the world.

"The majority of American voters would not like to see President Bush re-elected to another term according to a poll by Newsweek magazine."

Then I read the next sentence:

"The survey released Saturday showed that 49 percent of registered voters would not back the president for a second term if the vote were held now."

Since when is 49% a majority?
