Sen. Marco Rubio’s (R-Fla.) new book will be released in January, not long before candidates are expected to begin announcing their plans for the 2016 presidential race.

The book, titled American Dreams: Restoring Economic Opportunity For Everyone, is the Florida senator and potential GOP presidential contender’s second. It will focus more on policy, according to the Tampa Bay Times, than his first book, which shared his personal story as the son of Cuban immigrants.

White House aspirants have used book tours to raise their profile, reconnect with voters and lay out their vision for the country. They also come with monetary benefits as big-name political figures get significant advances for their books.

This summer, former Secretary of State Hillary Clinton embarked on a promotional tour for her newest memoir, Hard Choices. She appeared in front of supporters around the country and participated in several major interviews tied to the book’s release.

Ready For Hillary, a super-PAC devoted to supporting a Clinton bid used the tour as a chance to collect contact information from possible supporters. They followed the tour in a large, campaign-style bus and connected with supporters who came to hear the former top diplomat speak.

Clinton isn’t the only politician eyeing a White House run to release a book this year. New York Gov. Andrew Cuomo (D) released a memoir in October.

Others, like Rubio, are also preparing books for publication.

Sen. Ted Cruz (R) reportedly received a $1.5 million advance to pen a memoir and Maryland Gov. Martin O’Malley (D) is also rumored to be working on a book.
