Presumably the heavily Democratic areas had already reported and few if any of the heavily Republican ones had. It might seem illogical at a glance but it happens, and I've seen Dems declared winners who are behind in the votes that have been reported so far as well (if say the heavily urban areas haven't reported yet).
I've never ever ever seen this happen with a Democrat ever. However, in the 1988 presidential election, Illinois was called for Dukakis, only to be taken back later when DuPage County "found" a whole bunch of votes for Pa Bush.
Well Bush won Illinois by 95,000 votes approximately in 1988. Dupage turnout was only up 14,000 votes from 1984, so I think it's a bit of a stretch to say that turnout was actually at least 81,000 votes lower than it was in 1984 in actuality with the 95,000 extra manufactured votes....
Bush won Dupage by 123,000, which is down from Reagan's 155,000 vote margin in 1988. A Republican margin of only 28,000 in Dupage would've been lower than any Republican had won in that county since 1944 (and also lower than the Republican margin has ever been since 1988, despite Dupage's overall sharp turn to the left in the meantime), so again, seems a bit of a stretch.
