Charlie Gibson of ABC was interviewing four guys (all white, by the way) in Dayton, Ohio, about how the bad economic conditions in their area would sway their vote. One said that this was the first time in his adult life, but he was voting Democratic this year. Another one said, "I'm putting country first...and voting for Obama."
No one ever won the presidency in the past 11 elections without winning Ohio (which explains why the neocons tried so hard to rig the election in 2000)...and today Obama leads by six points in the state. Of course, four weeks is an eternity in politics, so you never know.
