George W. Bush (“Tumbler” or “Trailblazer”)
Because George W. Bush junior had two terms as President of the United States, he ended up going with two different code names to distinguish between the first period, and the one that followed. “Tumbler” referred to his cheerleading history, but close sources suggest it had more to do with his drinking habits. “Trailblazer” came in when he started the war in Iraq, which is a decision that seemed like the best course of action at the time, but has since been widely criticized.
Mike Pence (“Hoosier”)
Before he was vice president to Donal Trump, Mike Pence was governor of Indiana. For the duration of his 2016 campaign, the secret service referred to him as “Hoosier”, which is a nod to his hometown roots. The nickname was actually leaked to the media during this time, and it is unclear whether it was changed during her term. One code name that didn’t change was the one given to his wife, who was affectionately referred to as “Hummingbird” for the four years they were in office.
