I'm English so I don't know much about how your elections work, but looking at CNN it seems that there are nine counties in Montana still reporting:
hill moderate dem county
cascade moderate dem county
deer lodge strong dem county
glacier moderate rep county
flathead moderate rep county
fergus moderate rep county
judith basin moderate rep county
gallatin - even
lake - even

It shows how Montana voted in 2004.
Hill went 2:1 Rep.
Cascade went 2:1 Rep.
Deer Lodge went slightly Dem
Glacier went even
Flathead went almost 3:1 Republican
Fergus went even
Judith Basin went even
Gallatin was strong Republican
Lake was even.
The largest counties were Flathead and Gallatin. There are a lot of Republican votes still not counted in those counties.
