Iowa 500: Poll Positions at the Final Turn.

With Iowa coming up tomorrow, one last look at the Democratic polls: Reuters/MSNBC/Zogby has Obama and Clinton tied at 28%, with Edwards at 26%. CNN/Opinion Research puts Clinton in the lead at 33% to Obama’s 31% and Edwards’ 22%. And the Des Moines Register/Selzer’s last poll — considered the most trusted in the industry, partly due to its getting the 2004 results right — has Obama up big at 32% to Clinton’s 25% and Edwards’ 24%. (This result presumes a large independent turnout for Obama, however, which is by no means a given.) In any case, the one good bet is it’s going to be a barnburner tomorrow evening. Sometime before then, most likely by tomorrow afternoon, I plan to put up a longer endorsement-style post, since the nomination could well be a fait accompli by the NY primary on Feb. 5. No real surprise who I’m getting behind, but at least y’all will be able to poke holes in my reasoning.
