In looking at the results of last week's Iowa Caucuses, word of mouth advertisers should take careful note of the tactics used to draw powerful voices into the conversation. After all, to caucus, literally means to stage a discussion. To converse.

Watching the Democrats battle during such a tight race has been particularly interesting as party frontrunners employed smart tactics to get whole new audiences to join the caucus. They achieved their goal - itself a victory for this wacky part of the political process. But also for WOM marketers to appreciate.

While Obama ultimately attained the Democrats' nod in Iowa, Hillary Clinton really caught my eye in how she targeted and engaged female influencers. She identified boomer women as her best brand evabgelists, and embraced several marketing to women techniques. She deployed homespun, but notable devices to spark and perpetuate the "why Clinton" conversation at these statistically significant supporters' homes. Green shovels were used by staff to clear the path for snow-weary to join the events; lapel pins flagged the new caucausers for Clinton campaigners to embrace around town and literally at the events; mugs and refrigerator magnets took their place in kitchens to generate coffee talk. In my view, these likely generated hours of conversation. They did in my home - hundreds of miles away from Iowa.

In the New York Times, one political strategist scoffed at whether these tsotsckis would actually prompt someone to particpate. She didn't get the point. These were clever coversation starters on the block, in the kitchen and wherever the strategically selected supporter went throughout her day. Inspiration for marketers of any type.
