A national survey has found a majority of Americans cannot identify any of the democrats who’re running for president, and sometimes on the Iowa campaign trail even the democratic party activists have difficulty. Earlier this year, a supporter of Massachusetts Senator John Kerry told Radio Iowa she had supported Kerry when he ran for president before. When she learned Kerry hadn’t run before, the woman sheepishly admitted she didn’t know the difference between him and Nebraska Senator Bob Kerry. Then, on Friday, Kerry was being introduced by the mayor of Colo, Iowa who referred to Kerry as Senator Kennedy. The small crowd laughed, but the mayor didn’t know he’d called Kerry by the name of the former president and he kept on going before issuing a final sentence. “I’d like to introduce the next commander in chief, Senator John Ken, uh, Kerry,” the mayor said as Kerry threw his arm along the older man’s shoulder and laughed.
