In the days leading up to the caucuses in Iowa and the New Hampshire primary, some presidential hopefuls are getting an extra boost in the form of endorsements.
Just this week, The Boston Globe and the Des Moines Register recommended voters choose Democratic candidate Hillary Clinton.
Republican front-runner Donald Trump scored backing from evangelical leader Jerry Falwell Junior, as well as controversial anti-immigration sheriff, Joe Arpaio.
But how often do endorsements translate into votes?
Hans Noel is an associate professor of government at Georgetown University. He also helped pen the book, "The Party Decides: Presidential Nominations Before and After Reform."
He explained the role that endorsements have played in past primary elections, and what endorsements could mean to presidential candidates in 2016.
