DCorps: Cell phones — why we think Obama will win the popular vote, too

The following comes from a new Democracy Corps memo.
We will poll this week – awaiting the unfolding storm on the East Coast – but we want to share why we think the national tracking averages likely underrepresent Obama’s vote. The main issue is cell phones and the changing America that most are under-representing. Our likely voter sample includes 30 percent reached on cell-phones from a cell-phone sample conducted in parallel with our random-digit phone sample. Some other surveys have moved to that level and methodology, but most have not. They are missing the new America, and we’re not sure we are keeping up either.
In the real America, most Americans are now cell-phone only or cell-phone mostly users. With no one really sure what is the right proportion for the likely electorate, everyone has been cautious but that may be the riskier option.
Pay attention to this. In the last half of 2011, 32 percent of adults were cell-phone only according the Center for Disease Control that is the official source on these issues; 16 percent were cell phone mostly. But the proportion cell-phone only has jumped about 2.5 points every six months since 2008 – and is probably near 37 percent now. And pay attention to these numbers for the 2011 adult population:
More than 40 percent of Hispanic adults are cell phone only (43 percent).
A disproportionate 37 percent of African Americans are cell only.
Not surprisingly, almost half of those 18 to 24 years are cell only (49 percent), but an astonishing 60 percent of those 25 to 29 years old only use cell phones.
But it does not stop there: of those 30 to 34 years, 51 percent are cell only.
You have to ask, what America are the current polls sampling if they are overwhelmingly dependent on conventional samples or automated calling with no cell phones? Democracy Corps reached 30 percent by cell; 35 percent were cell only or cell mostly, but only 15 percent are cell only, well short of where we should be.
