Here's the first word on Exit Polls from Ohio, Texas, Rhode Island, and Vermont, as reported by The Campaign Spot:

This is interesting. One of my sources has gotten two sets of exit poll results. It's unclear whether this is different pollsters or, I suspect, different times of day.

For the first set, Obama is up by 2 percent in Ohio, Hillary is up by 2 percent in Texas, Hillary is up by 3 percent in Rhode Island and Obama is up by a 2 to 1 margin in Vermont.

The second set is similarly close - Hillary up by 2 percent in Ohio, the two Democrats tied in Texas, Obama ahead by 2 percent in Rhode Island and a similar 2 to 1 margin in Vermont.
