More on exit polling:
CBS News chief Washington correspondent Bob Schieffer said the exit poll numbers were similar to those seen in Virginia, a state Obama won handily as part of the Feb. 12 Potomac Primary.
“There can’t be very much happiness in the Clinton camp tonight,” Schieffer said. “She really is going to have her back to the wall now. Unless she does well in Texas and Ohio, I think this thing is about done for her.”
Obama won Virginia by 28 points – a Wisconsin victory by a similar margin would be huge, meaning he had encroached on Hillary’s core constituencies. Still, it’s important to warn that these numbers are early.
