Politicians are always looking for ways to catch people's attention.
But this year, some voters say they were tricked into answering phone calls about political campaigns.
Automated calls in some state House races displayed the caller ID of emergency facilities such as a hospital or ambulance service.
When people answered, they heard a recorded political message.
The bait-and-switch tactic is called "spoofing."
Northeast Missouri political candidate Keri Cottrell fell victim to this prior to election day 2010.
The U.S. House and Senate each passed different versions of bills this year that would outlaw fake caller IDs in some circumstances.
