Mark Blumenthal's piece examining the world of polling and the ways media outlets don't use landlines.
"This controversy raises two important questions: First, why are CNN's pollsters having so much trouble reaching younger Americans? Second, does it matter that CNN's landline sample misses so many younger Americans that it has to weight the youngest age group up by a factor of at least three?
The answer to the first question is easy: CNN's unweighted poll was light on younger Americans because their sample covered only households with a landline telephone. As documented by the National Center for Health Statistics, the percentage of American households with a cellphone but no landline telephone service has been steadily rising over the last ten years, especially among younger Americans. As of last year, 24.9 percent of all adults have wireless service only, but among those aged 25 to 29 years that number is now more than half -- 51.3 percent."

This is old news. Unless the article specifically says that cell phones were contacted, too, it can be assumed that only landline-respondents are used for the poll.
The reason: It is much more expensive to include cell phones so, if they did, it seems logical they would make a big point about it because it increases the validity of their polls.
However, for the polling groups who routinely use landline-only respondents, they will remain popular because conservative/GOP groups and candidates will use those polilng groups. The reason: landline-only polls turn out much more conservative than do polls that include cell phones.
In one poll there was a 13% difference ("more conservative" response) when a question was asked to a gorup of landline-users only and to a group that had both landline-users and cell-phone users, weighted for the percentage of population that each type.
The question was "Do you support cuts in Social Security?"
