I've been doing a bit of exploring on Real clear politics website

It appears a lot of news sources like Fox and Cnn use them
for numbers

I thought something was funny yesterday when Rasmussen put
out completly different numbers than most of the msm were quoting

Looking at the polls it seems real clear just runs a balance sheet
of several polls taken by the MSM media sources

And we of course know those are skewed all over the place

You will not get an accurate picture of whats happening from
most of the msm polls
