Beware of Polls That Exclude Cell Phone-Only Voters
— Watching the polls to figure out who's up and who's down this
election season? Be careful. The poll may have a pro-Republican bias.
The ranks of Americans who use cell phones only
have skyrocketed. Some public polls don't survey them, however, and they
miss a group of people who are more likely to vote Democratic,
including the young, the poor, Hispanics and African-Americans.
