Over the next 13 years, DeSantis’ signature would evolve from the neat cursive as a prosecutor to the hurried one he uses frequently today as Florida’s governor. Along the way, he dropped the middle initial. He altered the look of the “R,” and then switched it back. A quick squiggle and a big swoop replaced most of the letters in his last name... Some election officials say limiting signature samples could make it harder to authenticate the identities of those who vote by mail, perhaps leading to more rejected ballots. Signatures change over time, they say, and are often affected by the choice of pen, the writing surface, fatigue or a person’s health. DeSantis’ own John Hancock has undergone a transformation during his time in government, as demonstrated by 16 of his signatures compiled by the Tampa Bay Times from publicly available sources between 2008 and now.
