SurveyUSA: Clinton 50%, Obama 44%.

Late Commentary Update: What's interesting to note about the SUSA poll is that it shows not just a tightening of the race, as measured by SUSA, but a convergence of the polls. SUSA has been showing big double-digit leads. I'm pretty sure 6 points is the closest they've had this race. Meanwhile, the more traditional operator-run polls, which had been showing an even closer race, seem to have notched back a bit in this direction. By tomorrow morning we may have a relative polling consensus in the mid-high single digits for Clinton.
