In polls with live interviews and those that include cell phones, we get a better reading of how President Obama is doing.
In this universe, Mr. Obama seems poised for victory. The model forecasts him for a 4.1 percentage points win in the national popular vote. That compares with 2.9 percentage points in the regular FiveThirtyEight forecast, which includes polls both with and without cellphones.
Mr. Obama’s advantage is also clearer in the swing states. The cellphone-inclusive polls give him an 80 percent chance to win Virginia, a 79 percent chance in Ohio, and a 68 percent chance to win Florida, all considerably higher than in the official FiveThirtyEight forecast.
