My NationalJournal.com column for the week, on those widely divergent Pennsylvania polls, is now online. As a tease to motivate you to click thru, here's the graphic featured in the column (graphically enhanced by my National Journal colleagues).
I should note that while I was writing this column yesterday, Brian Schaffner was apparently in the midst of creating a scatter plot for his CCPS blog that is eerily similar to the one I did for the column. He gets all due props for getting his posted first.
[I've got some additional thoughts that were too much for the column and will update with those a little later this morning].
