Will Joe Biden run for president in 2016?

Joe Biden appears to be keeping his options open for 2016.

The vice president is dropping hints that he may be laying groundwork for a presidential campaign.

He packed his schedule with events and receptions attended by party insiders surrounding President Barack Obama's inauguration.

Biden met with Democratic National Committee members during a private reception Tuesday. New Hampshire Gov. Maggie Hassan was among the guests at Biden's swearing-in ceremony, and the vice president dropped by an Iowa inaugural ball. Both states are important in early presidential voting.

Biden told CNN there were a lot of reasons he wouldn't run and said he was focused on helping Obama.

Secretary of State Hillary Rodham Clinton remains a heavy favorite for the Democratic presidential nomination if she decides to run.

Biden has a law degree from Syracuse University and spoke at SU's 2009 commencement ceremony.
