NEW YORK (AP) -- A new ad showing Herman Cain's smoking campaign manager is the latest political video to become an overnight Internet sensation.
The ad has had nearly a million clicks on Cain's website since its debut last week. It's also been aired repeatedly on cable news shows and has become the subject of countless parodies.
Online viral videos have become a staple of American politics. Not long ago, pricey paid television ads were the only way for candidates to be noticed.
But one expert whose company tracks political advertising says that while online videos have the power to influence a race, paid television advertising still carries more impact overall.
