Another step in Charlie Crist's political evolution is complete. On Wednesday night, the former Florida governor endorsed gay marriage.

"I most certainly support marriage equality in Florida and look forward to the day it happens here," the Republican-turned-independent-turned-Democrat wrote on his Facebook page. He congratulated Delaware on becoming the 11th state to legalize gay marriage.

Crist, who became a Democrat in December, is considered a potential candidate against Gov. Rick Scott (R) in 2014. Polls suggest he could easily beat the sitting governor. But questions have lingered about his record on gay rights; in 2006 he signed a petition in favor of a constitutional amendment banning gay marriage and adoption in the state. He reaffirmed his support for the ban in 2008.

Shortly after announcing his party shift, Crist said that he regretted signing that petition but stopped short of endorsing marriage.

In his Facebook post, Crist did not discuss when or why his personal views on the issue have changed.
