If Burns can maintain the 51-47 advantage in Yellowstone he'll pull it out, he's gain anothr 2000 votes in Yellowstone, and he'll gain another 1500 in the other uncounted districts if forms hold in those as well.
He's lagging in Gallatin versus 2000 by a lot - but Gallatin has Republican and Democrat-leaning precincts. If the Republican precincts are still out and Yellowstone keeps it up, Burns will win handily.
