Gallup
reports that Barack Obama's 7 point bounce after presumably clinching the nomination has all but vanished into a statistical tie with McCain at 44-42. Fifteen percent of those polled do not back either, with 8 percent stating they will not vote for either.
Richard Baehr adds that
Rasmussen also shows the Obama lead softening, from 6 points Sunday to 4 today. Gallup and Rasmussen both use rolling averages. [corrected.]
