12. I do yougov surveys

Not this one wasn’t asked lately about politics but I can tell you from all have taken in the last 15 years, they used to be polling point, every survey asks what party you belong to, then if you say democrat they ask strong one! They ask specifically if you voted in 2016, 2018 and will you vote next year, in primary and who for.

I have taken these at least once a month or two for years so they know obviously who is going to say what so they can screw the polls around.

I am sure people change their minds but it cant be that often especially if you have been with them a long time.

Based on this not sure I trust polls. Most of the surveys I do are for products but I enjoy the political ones. Sometimes they push poll asking in such a way to get a certain response. Makes me angry and i always complain at the end where you can comment.
