Don’t put much stock in this, since all very subjective and anecdotal (and turnout scuttle-butt is of even less use than exit polls): Chafee campaign thinks they’re definitely getting out the Chafee ID’d voters; turn-out is reported to be high in the “T” in PA that is so important to Santorum; Republicans feeling good about their GOTV in MO and MT.
In general, turn-out seems high everywhere–it’s going to be a high turn-out election. Fwiw (not much, I know).
