If you flip on a local television station and watch for an hour or so, you're likely to see at least one: a political ad that attacks a local or national candidate.
If you live in any of the "battleground states," you'll see many, many more -- up to 12 political ads an hour.
Viewers in Iowa fell under a barrage of these ads leading up to Tuesday's caucuses. This on-air onslaught offers the rest of us a preview of what television viewing will be like as Election Day 2012 draws closer.
It's estimated that American television viewers will see such political ads aired more than 200,000 times by the first week in November. What we're
far less likely to see is any explanation of who
really sponsors these ads, what interests they represent and whether the content of the attacks is true.
