A presidential candidate only needs 270 votes in the Electoral College to win, and if Emerson College Polling is accurate—Hillary Clinton will far surpass that amount.

Emerson College is predicting the Democratic nominee will win 323 to 215.

How do they figure?

Emerson took into account recent polling results in battleground and other states, combined with RealClearPolitics polling averages. Emerson predicts Clinton will win the swing states of Colorado, Florida, Michigan, Nevada, New Hampshire, North Carolina, Pennsylvania, Virginia and Wisconsin. Republican nominee Donald Trump is predicted to win Iowa and Ohio.

The college also predicts Democrats have a very good chance of taking back the Senate.

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.

Here's what their projection map looks like:
