CNN Polls - Is There an Agenda Behind Them?

Has anyone else noticed, how predictable the outcome of CNN polls are? I know every time which poll option will get the most votes. Most of the time I can guess with an error margin of about 7%.

I find it very fishy that their polls are so easy to determine. Almost like they are fabricating the results to push an agenda forward. So, what I'm saying is ... I think they are trying to brainwash to populous into thinking the majority is actually the minority. Or is it something else? What do you think?
