What do we know so far on Big Love season 4? The promos don't really say a lot, although they're deliciously vague and mysterious, except that falling might be the keyword on the season that kicks off January 10. Of course, falling apart is the most obvious guess, but from where people stand right now, there ought to be more than that.

First off, Bill (Bill Paxton) is running for state senator to openly promote polygamy. According to Big Love executive producer Marc Olsen, Bill's objective is to be public polygamists. "He can't be impeached for that. Polygamy is technically a misdemeanor in Utah, [and a misdemeanor is not] an impeachable offense," he says, adding that the family isn't exactly united on whether or not to support his political bid.
