Yes, that's what I was asking.
We can get people's land line numbers from online directories—since actual phone books have all but disappeared—but cell phone numbers are considered confidential and we don't have access to them. Not being able to communicate with voters is problematic in many ways, and it's getting worse every year. As people die, the proportion of land lines drops between 1% and 5% a year. Young people own only cell phones. In 15 years, just 20% of the population will be accessible to us by phone.
Should we raise the red flag to say that it's time to do something about this situation? It's a genuine problem, after all.
