Rejecting both Hillary Clinton and Donald Trump, Maryland Gov. Larry Hogan wrote in his father, former Rep. Lawrence Hogan, as his choice to be president.
Doug Mayer, Hogan's spokesman, said Tuesday the Republican governor voted early.
Hogan had said for months that he wasn't going to support Trump. He said he had been extremely disappointed in the candidates from both major parties.
Mayer said the governor decided to write in the name of the person who taught him what it meant to hold public office with integrity.
The governor's father was a Maryland Republican congressman from 1969 to 1975. He also was Prince George's County executive from 1978 until 1982. He is 88.
