The Impact of Political Endorsements

Newspapers do it, labor unions do it, movie stars... even baseball players do it -- endorse candidates, that is. But the question is, does it matter? We'll take a pre-election look at who's endorsing whom, and what endorsements mean to you.

Guests:

Tom Rosenstiel, director of the Project for Excellence in Journalism.

John Porter, editorial page editor, The Portland Press Herald (Maine).

Bob Silbernagel, editorial page editor, The Daily Sentinel.
