Crist attached a picture of him holding his voter registration as proof in a tweet that read, “Proud and honored to join the Democratic Party in the home of President @BarackObama

The former Republican governor-turned independent Senate candidate’s move was expected, according to the Washington Post. 

The Christian Science Monitor reported that while Crist’s overall record is more liberal although he has historically been strong on gun rights and primarily anti-abortion.
