I have noticed a lot of sample manipulation in recent phone polls which I have answered.
After you are done answering to the main poll questions, they ask a series of demographic questions, supposedly to ensure even distribution of various groups.
The most recent one was really invasive, i.e. your religion affiliation answer caused a salvo of irrelevant questions like how often do you go to your church. The only reason for such curiosity is to make you impatient and drop the call, therefore making your answers to the main questions void.
Resist the temptation and answer fully to make your voice heard!
Also, I claimed to be an 18-29 year old Pacific Islander girl with no party affiliation - let them try to dismiss that! :)
You probably also need to be a transgender lesbian (male lesbian?) as well, just to make sure. :>)
Party affiliation? Republican.
