To do a little results-related cleanup:
The best analysis of the W.H. race probably has to wait on precinct and county-level data to supplement the higher-quality modeling and polling used by the campaign(s) and party committees, but no need to wait on Senate and House races. In the House, two illegal GOP gerrymanders getting tossed in VA/FL led to one guaranteed Dem pickup (VA-4), a trade (GOP-held FL-10 for FL-2), and various seats gaining an edge one way or the other. The GOP gave themselves more of an edge in FL-18 and was able to pick it up, their only other gain outside of NE-2. Remapping forced them to make FL-7 and FL-13 more Democratic and as a result Democrats picked up both.
Dems also retook IL-10, NH-1, NJ-5, NV-3 and NV-4. And with votes left uncounted in California, Dems only trail by roughly 4k votes in CA-49.
In the Senate the Democrats easily retook IL and narrowly retook NH, and held both CO/NV. The Dems could never answer the flood of billionaire money that Republican donors were pouring into these battlegrounds over the last year, and huge last-minute injections especially helped the GOP hang on in PA/NC/WI. A couple of Democrats did put together some ridiculous overperformances in losing efforts, especially in MO (Jason Kander only lost 49%-46% in a state Trump carried 56%-37%) and and FL (Patrick Murphy only lost 51%-45% after being outspent 18:1 from September onward).
The new Senate composition as of right now is 51 Republicans, 48 Democrats+Independents, and 1 outstanding (LA). Republican Treasurer John Kennedy and Democratic Public Service Commissioner Foster Campbell advanced to the December 10th runoff to fill the 100th seat.
