Certain issues play well to the public. Others do not.
For example, health care issues don't get as much press as guns, grass and gambling. Alcohol too. Call me cynical, but politicians cannot get the mileage from breast cancer that they can from guns. So, they go with the percentages and talk about guns.
Look at this chart from 1992, when the gun debate was raging.
Death by cancer -- men - 30,481
Death by homicide, firearm -- men - 178
Death by cancer -- women - 25,167
Death by homicide, firearm -- women - 69

Causes of Death in Canada
What got more air time on the Internet, in newspapers, magazines, television and radio? The 55,648 cancer deaths or the 247 gun deaths?
Guns grab everyone's attention because the airwaves are full of news footage about wars around the world and fictional dramas that use handguns, like cop shows or mysteries. Politicians know this and will talk about guns because it stirs up so much rancorous debate. It gets their name in the news and in front of constituents.
How often is any kind of cancer featured in the news or on a television show? How often do politicians makes statements about cancer? Sadly, cancer is a political non-event.
Marijuana is like the gun debate. It gets a lot of air play.
