Five seconds into this ominous looking political commercial against Harry Reid, the American Crossroads narrator says, “Wait a minute. Are you tired of all these negative ads?” He then turns to the camera and matter-of-factly delivers the same message the group has been sending out over the Nevada airwaves all campaign season. The music is nicer, too:

This ad is part of American Crossroads’ effort to help elect Republicans in key races. In early October, the group announced it would spend nearly $800,000 in Colorado and $350,000 in Nevada. Crossroads Grassroots Policy Strategies (GPS), an affiliate of the same group, has also been buying time in Illinois, Washington state, Missouri, Kentucky and Pennsylvania. The two Crossroads groups have said they plan to spend $50 million combined this campaign season.

Crossroads’ spending is making national headlines as journalists observe the electoral efforts of third party groups attempting to help both political parties. As a whole, these groups will spend an estimated $500 million on the mid-term elections, according to a recent estimate by the Center for Public Integrity.
