N.B. This listing includes mostly media and public polls; party or candidate polls are generally not used unless other polls are unavailable. Because all polls have a margin of error in their numbers, the polls should be taken as useful indicators at the moment the polling is conducted rather than absolute truth. In some instances, conflicting polls are provided.
