Rasmussen acknowledged errors and changed his methodology for 2004.. Zogby was experimenting with an internet-based polling system in 2004.
I am in the zogby poll. I tell them I am a democrat, union member, do not own a gun, do not consider myself in the "investment class", voted for kerry in 2004, and every other question to make me look like a democrat.
I've been telling them for months that I was voting for Obama.
I plan to start telling them Mccain next week.
This will maximize my effect on the poll. I'll get more weight as a democrat.
