Yes she can

Hillary Clinton, the person who won three million more popular votes than Donald Trump, has every right to continue to be part of public service if she likes. As has been pointed out, did Al Gore, John Kerry, John McCain, and Mitt Romney fade into the background after their losses? With her three million popular vote victory in 2016, she actually deserves a shot at the Presidency again. She may not take it but no one should be surprised if she wanted to.
