I dowloaded this applet and played around with some questions. The questions are definitely skewed Trump or the users of the App are conservative. For example, question asked, “Who will be better for the middle class”. Trump 92% Clinton 8%. In a standard poll, that is a strong Democratic question. I understand the confirmation biases inherent in some forms of social media but take this app with a grain of salt.
The fact is they predicted Trump would win the primaries and that England would separate from the EU. The interview is very very good.
