"All responses in the sample should be treated as opt-in Internet panel even though a percentage of respondents were specifically targeted based on registration status (more on that below in population). They are still ultimately considered opt-in and we do NOT treat them as a random sample."
I.e., it is bullshit, meant to be spoon fed to suckers.
"We cannot accurately estimate a margin of error (MoE) because the sample is not a probability sample that used a random selection."
I.e., We know our own results are shit, it is solely clickbait for the less intelligent of the world.
Guess they were just lucky with their ‘fake’ polls in 2014.
