In this case, DialIdol (unavoidably) has a methodology error because they don't take text messaging into account. They also rely on their users being a representative sampling of the country, but it is a self-selecting group, and that laways introduces some form of bias.
"Trusting DialIdol is lot like trusting exit polls."
That's a good point...although they're a bit better because with exit polls you have to take the liberal bias of the media into consideration.
