* From a July 6-10, 2016 Anzalone Liszt Grove Research poll of 606 likely Illinois voters when asked about their cell phone usage…

* Every responsible pollster has already taken note of this trend and adjusted accordingly. So, this move is no surprise…

As more Americans have made a mobile phone their main phone, polls that contact only landline phones look increasingly behind the times. HuffPost Pollster has decided we need to evolve.

By the end of last year, 48 percent of American adults didn’t have a landline phone. Another 16 percent had a landline but relied mostly on their mobile phone to make and receive calls.

That’s 64 percent of Americans who are only or primarily reachable via mobile phone. The numbers go even higher for those under age 45 and for minorities. Sixty percent of Hispanic adults don’t have a landline at all, and more than two-thirds of Americans between ages 25 and 34 rely solely on a mobile phone.

HuffPost Pollster has always sought to base our charts on as many sound polls as possible. As long as a pollster makes a good-faith professional effort to obtain a representative sample of the population, we include the survey’s results. In our opinion, polls that call only landlines with no attempt to sample the other half of the population no longer fit that description. So from now on, we will no longer include the results from landline-only telephone polls in our charts.

* So, consumer beware. If you see a published poll and it doesn’t include the percentage of mobile phone respondents, you can safely assume that there are no mobile phone respondents, particularly if it’s a robopoll. And media outlets that publish telephone poll results from surveys which don’t include mobile phone users are either clueless or living in the past.

Demand better.

*** UPDATE ***  And right on cue…

A recent poll commissioned by The Illinois Observer shows Governor Bruce Rauner losing in a hypothetical re-election matchup by nine points.

Illinois Working Together Campaign Director Jake Lewis released the following statement regarding Governor Bruce Rauner’s sagging poll numbers:

“It’s no surprise that the vast majority of Illinoisans would not re-elect Governor Rauner. After all, it was Bruce Rauner’s reckless pursuit of his radical, anti-worker agenda that created a crippling and unnecessary budget impasse, devastating the state’s social safety net. Governor Rauner’s term in office has been a total failure since Day One, and the harm that he has inflicted on the people of Illinois may take years to heal. Illinoisans are sick of the governor’s divisive brand of politics that has achieved nothing except causing widespread damage to Illinois’ seniors, families, and economy.

“Though the 2018 election is still some time away, it is clear that Illinoisans have already rejected the extreme Rauner agenda. It is now up to the governor to listen to the people and drop his demands once and for all.”

The “poll” is problematic for numerous reasons. First and foremost, the pollster’s identity isn’t disclosed, which is highly unusual. Second, there is no disclosure of the type of polling that was done, live calls or robocalls. And third, no stats were disclosed on mobile phone users, if any.
