You don't understand how polling works and why the good pollsters can be right the vast majority of the time. I have taken some statistics courses and the construction of polling samples. Internal polls are used extensively by politicians and the government. Don't underestimate their validity and usefulness.
When you've normally had 50% and higher response rates and new technology drops you to a 9% response rate at best, you really no longer have something that is under statistical control and you can't say it's reliable.
The fact you would even begin to argue with me on the point is a demonstration you don't know anything about statistical sampling, whether for opinion, profiles or quality control
