How a swing state running mate could help Trump or Clinton win the White House

With the general election season now upon us, both Hillary Clinton and Donald Trump are considering who to pick to be their Vice President. In new research, Boris Heersink and Brenton D. Peterson argue that to help them win the presidency, the candidates should consider someone from a swing state. Why? They find that, in contrast to previous studies, a running mate can increase a presidential ticket’s support by nearly 3 percent in a Vice President’s home state, something which could have swung four elections since 1960.
