Via press release:
Amidst a general tightening of the race in key battleground states and a pattern of both Democratic and Republican voters coming home to the major-party candidates, Emerson College Polling is predicting that Hillary Clinton will win the Electoral College by a lopsided margin of 323-215. The map, shown below, reflects recent Emerson polling results in battleground and other states, combined with RealClearPolitics polling averages in those states Emerson has not surveyed.
In battleground Senate races, Emerson also projects that Democrats will come out of the election with 50 or more seats. That would be enough to claim a Senate majority if Clinton is elected and Tim Kaine, as Vice President, becomes the tie-breaking vote. Our final round of polls suggest that the following Democratic challengers will flip GOP seats in four states: Tammy Duckworth vs. Mark Kirk in Illinois, Russ Feingold vs. Ron Johnson in Wisconsin, Jason Kander vs. Roy Blunt in Missouri and Katie McGinty vs. Pat Toomey in Pennsylvania.
