Cook submits final predictions:
The Cook Political Report's pre-election House outlook is a Democratic net loss of 50 to 60 seats, with higher losses possible.
In the Senate:
The Cook Political Report is adjusting its current outlook to reflect a net gain for Republicans of 6 to 8 seats, down from 7 to 9 seats. While it is becoming increasingly likely that Republicans will hold all 18 of its own seats, Democrats' prospects in three of their 19 seats have improved in recent days. Sens. Barbara Boxer in California and Patty Murray in Washington now appear to be headed for re-election, albeit by small margins. In the special election in West Virginia, Democratic Gov. Joe Manchin now holds an advantage. Currently there are 57 Democrats, two independents that caucus with Democrats, and 41 Republican Senators. Post-election, Republicans could hold between 47 and 49 seats to 51 to 53 seats for Democrats. This new outlook means that the odds of Republicans winning a majority in the Senate are now non-existent.
