Hillary Clinton is not the first person to get on LinkedIn — about 115 million Americans joined before her. Nor is she the first 2016 contender. Marco Rubio, Ted Cruz, and others already have profiles there.
"The difference between Hillary Clinton and every single other candidate running, including Jeb Bush, is she has universal recognition already," says Larry Sabato, the director of the Center for Politics at the University of Virginia.
This argument is similar to the one being made by her campaign. They say everyone knows her name, but few know the real Hillary.
