WASHINGTON (AP) - Don't like the latest poll numbers on the presidential race? Just wait. More are coming - probably before you can say "margin of sampling error."

Regardless of what any given poll says, it's likely that someone - a campaign, an interest group, a political party or a rival polling operation - will argue that the survey is invalid at the same time someone else argues that it's significant.

Polls have become political tools and have taken on outsized importance as they've become easier and cheaper to conduct.

A part of campaigns grounded in science, polling has lost some of its standing as a neutral record of voters' attitudes and opinions, and, at times, has become just another talking point.
