A good reminder of the peril of reporting polls:
This morning we posted an item about a new Quinnipiac poll showing Obama within 6 of Clinton in Pennsylvania, and mentioned that six consecutive Keystone State polls have shown Obama gaining ground and within 6 points behind.
Now: A SurveyUSA poll comes out. It has Clinton ahead by 18:
"The complete absence of movement among whites and among women is striking. Among white voters, Clinton polled at 61% in all 3 tracking polls. Among women, Clinton was at 62% a month ago, 62% last week, and 61% today. These two unwavering core constituencies help make Clinton so formidable in the Keystone state."
So: No trend. Confusion.

The 18 poll isn't polling the same population as the other polls. The other polls are polling "likely voters in the democratic primary". This poll is polling "adults".
polled=1600///of those, 1407 registered (no note what party)///of those 597 "likely to vote in democratic primary in PA.
With almost two thirds of polling population used not "likely to vote", it would be very easy for others to skew this poll i.e. Republicans, people with prejudices, etc. etc.
