A panel survey. If you noticed it started out with more Trumpers.

It's the same people every time, so if they got a sample with more Trumpers initially and keep recontacting the same people of course Trump still leads.

It's predictive power, because of that, is zero.

It may even call itself a poll. It was a poll the first time it was taken. After that it's a recontact survey.

If you contact the same group of individuals over and over again, all you measure is the bias of that *contacted* group. Contacting random groups from a larger sample space though lets you estimate the inclination of the entire population.
