The Home State Effects of a Running Mate Pick

Larry Sabato’s Crystal Ball: “If Harris picks a running mate from a true swing state (like Arizona or Pennsylvania), it would be unusual, at least considering recent history, as most recent picks have not come from states at the center of the electoral map.”

“Research is mixed on the home state bonus afforded by running mates; if any effect does exist, it is likely small—although just a small effect could be decisive in a key state.”
