It's in the "stars" (predicting by astrology and other means)

[Eric the Green]

Beware running for president if you have a Saturn Return coming during the election or in the next four years from election day, and before your opponent does.

Classic incumbents who were booted out, as indicated by the Saturn Return:
Martin Van Buren, 1840
Benjamin Harrison, 1892
William Howard Taft, 1912
Herbert Hoover, 1932
Jimmy Carter, 1980

Classic losers who had the Saturn Return coming:
Andrew Jackson, 1824
Henry Clay, 1832
Millard Fillmore, 1856
Horatio Seymour, 1868
Winfield Scott Hancock, 1880
Charles Evans Hughes, 1916
Al Smith, 1928
Adlai Stevenson, 1956
Barry Goldwater, 1964
Hubert Humphrey, 1968
Walter Mondale, 1984
Michael Dukakis, 1988

Incumbents who were booted out, but didn't have a Saturn Return coming (but....):

John Adams, 1800 (no popular vote taken; plus his score was lower than Jefferson's, whom he had beat last time)

John Quincy Adams, 1828 (but he had beat Jackson in 1824, who had a Saturn Return before Adams' Saturn Return just before 1828; Jackson also had a higher horoscope score)

Grover Cleveland, 1888 (but Cleveland won the popular vote, and beat him in a rematch in 1892; plus Harrison had a higher horoscope score)

George H W Bush, 1992 (but Bill Clinton had a higher horoscope score, and Bush also faced Ross Perot)

In 46 out of 57 elections, the winner had a higher score than the loser. In the 11 cases where the loser had the higher score, 7 of them also had a Saturn Return (Jackson, Van Buren, Fillmore, Hancock, B. Harrison, Goldwater, Carter)

4 candidates had a higher score, and NO Saturn Return, and still lost:

Adams 9-5 beat Jefferson 7-0, 1796 (but Jefferson won the rematch, and was re-elected)
TR 13-13 beat Parker 17-8, 1904
Taft 12-9 beat Bryan 8-3, 1908
JFK 13-6 beat Nixon 17-6, 1960

In the latter 3 cases, the new moon before election favored the winner. (in 1800 and through 1848, the new moon was not a factor because the election was held over a 5 or 6 week period)

Plus, TR and Taft had Jupiter rising.

Jupiter rising in the chart of a candidate almost always signifies a winner. Again, you have to look at balancing factors though.

Winning candidates with Jupiter rising (J):
Polk 21-2 J beat Clay 6-13, 1844
Lincoln 15-2 J beat Douglas 13-18, Breckinridge 2-23 J and Bell 4-15, 1860
Lincoln 15-2 J beat McClellan 13-13, 1864
Grant 16-4 J beat Seymour 6-12, 1868
Grant 16-4 J beat Greeley, 4-13, 1872
TR 13-13 J beat Parker 17-8, 1904
Taft 12-9 J beat Bryan 8-3, 1908
Johnson 10-7 J beat Goldwater 19-9, 1964
Bill Clinton 19-2 J beat George HW Bush 15-4, 1992
Bill Clinton 19-2 J beat Bob Dole, 13-21, 1996

Who lost with Jupiter rising?

Major party candidates:
Taft, 1912, who also ran against both TR (Jupiter also rising) and Wilson
Mondale 10-13, 1984, who ran against a much-higher scoring candidate, Reagan 19-5

3rd party candidates:
Breckinridge, 1860, whose raw score was the lowest of any candidate in history, 2-23
George Wallace, 1968, who had a dismal 2-6 score.
TR, who ran against both Taft and Wilson.

In this election, Hillary Rodham Clinton has Jupiter rising, and a 12-9 score (just like Taft). Trump has a score of 8-4 (much like Bryan). The new moon favors Hillary (just like 1908). It's a close decision. On balance, Hillary is favored.

No candidates who ran in 2016 have a Saturn Return coming, except Rick Santorum. However, some who didn't run, do. Roughly, all those born between 1957 and 1960:

Mike Pence, score 9-9
Tim Kaine, 13-9
Terry McAuliffe, 11-3
Mark Cuban, 8-10
Andrew Cuomo, 12-6
Janet Napolitano, 12-5
Rahm Emmanuel, 12-12
Bob Casey, 4-10
Jack Markell, 11-7
Amy Klobuchar, 6-9
