by D. Cupples | Pre-election polls don't necessarily reflect how voters will actually vote (e.g., some polls before the California and New Hampshire primaries). Because many people enjoy looking at polling data (and I like to create a record, so I can look back and see how far off some polls were), I've listed below some data from recent polls re: the Democratic primaries in Ohio, Texas, and Pennsylvania.
OHIO (March 4)
...........Rasmussen....SurveyUSA....Ohio Poll....PPP....Quinnipiac....ARG
Clinton.......48%................50%................47%...........50%........51%............49%
Obama.......43%.................44%................39%............46%.........40%............39%
