DENVER • They're as common at campaign stops as colorful banners: hand-held cameras wielded by politicians' opponents to catch them making a stupid mistake.
So how come candidates keep getting tripped up by "trackers" recording their every move?
Trackers have been credited for spoiling campaigns from Virginia to Nevada. Amateur video clips could make the difference in Colorado's GOP Senate primary on Tuesday.
Just ask Ken Buck, a rural prosecutor with a strong Tea Party following whose surging campaign was recently tripped up by gaffes that were caught on tape and quickly became online sensations. In one, a Democratic tracker recorded Buck saying, "Will you tell those (expletive) at the Tea Party to stop asking questions about birth certificates while I'm on the camera?"
