President Trump has a huge decision to make: Should he keep Vice President Mike Pence as his running mate, or consider other options that may yield renewed vigor into Trump’s voting base?

Most incumbents keep their vice president for another term, but there have been several instances where new running mates were selected to best wrangle their party’s support for a second term. The last time a sitting president didn’t run for reelection with his vice president was 1976, when President Gerald Ford ran with Bob Dole instead of Vice President Nelson Rockefeller (though the circumstances of Ford’s presidency were obviously unique). With the final year of a presidential term as chaotic as this, including an impeachment trial, economic crash, and a pandemic (and it’s only April), Trump must exhaust all available options to unite and expand his base of support.
