This blog's favorite ballot initiative of the year -- the Denver measure to establish a city commission preparing for the city's defense against extraterrestial attack -- has legs. (Don't ask me how many legs). Its sponsor has called a press conference for Friday to unveil a video of a space alien. Your blogger wonders if the alien going to endorse one way or another on the initiative? Denver has such a low signature gathering threshhold -- less than 5,000 -- that this measure could make the ballot... One thought submitted by a reader. Perhaps Houston needs something similar. After all, it was the Texas city, not Denver, that was totally destroyed in the alien attack in the 1996 film Independence Day.
