I dunno...I think the Republicans are going to stall out around 48 seats. Just a gut feeling.
One very interesting note: a number of states have minimum wage hike ballot initiatives in play, and they're all passing. Even in blood-red states like Nebraska, they're passing with about 60-65% approval. Republicans simply can't defend their opposition to a national minimum wage increase when their core states are passing them.
EDIT: NC race has flipped to Tillis at the moment, by a margin of about 10,000 votes with 68% reporting. I'm really hoping late returns from Charlotte and Raleigh will flip that shit back around.
DOUBLE-EDIT: Okay, here's how the Senate margin boils down at this point:
Iowa
North Carolina
Louisiana
Alaska
Kansas
If Republicans win 3 out of 5 of these, it's a 50-50 split and Biden serves as the tiebreaker. If they win 4 of 5, they take control.
At the moment, Roberts is slowly pulling ahead of Orman and looks set to win in Kansas. NC is still way too close to call. LA is probably headed for a runoff thanks to
le politique Acadien. AK and IA haven't reported in yet.
We're probably not gonna know who has control for a good long while, especially if Dems win in IA, AK or NC. The Lousiana runoff wouldn't be until AFTER the new Senate is seated, which will lead to all sorts of weirdness. Also, means that if the whole shebang hinges on the Louisiana runoff election, you're going to see an absolute metric fuckton of money poured into that ad market over the Christmas season. :-/
