Crist, who previously served as the governor of Florida, left the Republican Party and became a Democrat in 2012, suggesting that he was too moderate for what the GOP had become.

The one-term governor won his House race in 2016 after a string of unsuccessful bids for public office, including a challenge to then-Gov. and now-Sen. Rick Scott (R) in 2014.

Crist argued in the op-ed that Biden stood the best chance of beating Trump due what he said was the former vice president's appeal to independents and Republicans frustrated with the current state of their party.

Biden's campaign has touted his electability, citing his connection with working-class voters, as well as his more moderate stances on issues like health care.
