More on the SurveyUSA poll

The crosstabs are up now on the SurveyUSA poll and there's already one pretty clear explanation for the bizarre numbers. The party identification breakdown on the poll is 41% Republicans, 40% Democrats, and 16% independents.

A month ago SUSA found a 46-33 Democratic party identification advantage. Although it is possible there could be some shift after the Republican convention a 14 point shift strains credulity. PPP has found a Democratic id advantage of anywhere from 8-15 points in its general election polls, and I think Civitas has found an id advantage of 11-13 points pretty consistently.

I am not one to trash Survey USA- I think they are a top notch company, but we all have our bad polls and I suspect for them this is one of them. We'll have new numbers tomorrow.
