Looking at what's left out there in Montana:
Cascade should give Tester another 500 votes net.
Fergus should give Burns about 1000 net.
Gallatian should give Burns, maybe, 500 net. Or be a wash.
Lincoln should be worth another 1000 net for Burns.
Megher a couple of hundred.
So, yeah, he needs a good result out of Yellowstone to win, at this point.
So basically, we're looking at a 4,000 vote lead for the RAT, which should be whittled down to 2,000 lead ex Yellowstone County.
Burns took Yellowstone by 2,600 votes six years ago, but is sagging by a point or two elsewhere. Seems like it's going to be excruciatingly close.
Watch Burns pull it off because of Yellowstone County and the RATS make a huge to do about the recount there.
