Sabato says most of the races look like toss-ups to him. He's not calling any as even leaning Democratic at this point. "It's very hard to predict just where the (Democratic gubernatorial candidate Terry) McAuliffe-led Democratic wave may crest," said University of Virginia political scientist Larry Sabato. "It may be a very small breaker, carrying only one or two of these seats on election night. Or it could be a tidal wave, taking as many as seven or eight of them."
