Donald Trump is one of the most divisive leaders, at home and abroad, in American history. His humble bid to win another four years in the White House will be the most watched election in history. He’ll like that. But how does America actually elect its president and what role is played by the mysterious electoral college?

In Tuesday’s Child: How America Chooses Its Presidents, Church looks at the historical background of the electoral college and how it works today. In what becomes fifty individual elections, Church shows how candidates can choose which states to woo (or ignore) in their quest to amass 270 electoral college votes out of the 538 available.

This book takes a fun look at election statistics, examining if tall candidates beat small, young defeats old, Virgo edges Sagittarius and bad hair trumps good.
