A proposal to ban traffic cameras in Iowa is receiving a majority of the support in a new poll. The Des Moines Register/Mediacom Iowa Poll found 53 percent of those surveyed support a ban on traffic-enforcement cameras while 41 percent don't like the idea. Six in ten Iowans under age 35 support the ban while Republicans in the survey were split down the middle. There is a bill moving through the legislature to ban the cameras, but there is also a bill that allows cities to keep the cameras.
