What graphic are you talking about? And this disclosure is part of the text: "Mason-Dixon Polling & Research, Inc. of Washington, D.C. conducted these polls from October 15 through October 18, 2004."
Read the analysis story linked in post 81. It clearly states these are brand new polls!
Ok...
As it turns out, it seems they ARE all new polls....the numbers are different from the previous M-D polls.
Still, MSNBC sort of botched updating the text.
