Political Ads

POLITICAL ADS….Via James Joyner, here’s a head-scratching result from Gallup. As the chart on the right shows, conservatives say they trust candidate ads more than advocacy ads from interest groups. Liberals trust advocacy ads more than candidate ads. The Gallup press release is here.

Any guesses about why this might be? Is it because “advocacy” is more associated with groups like the Sierra Club than the NRA? Is it because liberals and conservatives have a different view of what advocacy is in the first place? Or do conservatives just trust political candidates more than liberals do?

It seems like this should lend itself to plenty of good pop psychologizing, but nothing springs immediately to mind. Any ideas?
