If independent Dan Osborn really does beat Sen. Deb Fischer (R-NE) by 4-5 points, it will be one of the greatest upsets in modern political history. If Osborn wins (and we have serious doubts about that since Fischer is a generic Republican in a red state who is not involved in any scandals), he could potentially determine which party controls the Senate. For example, if Kamala Harris wins and there are 49 Democrats, 50 Republicans, and Osborn in the Senate, whichever party he caucuses with will get to elect the majority leader and control the Senate. If this situation happens, Nebraska will go from being an all-corn state to an all-pork state and Sen. Manchin (I-WV) will start banging his head against the wall and mumbling: "Damn, damn, damn. Why didn't I think of that?" (Z)
