Barack Obama has joined LinkedIn, asking the LinkedIn community about what the next president can do to help small business. Back in January, Hillary Clinton asked Yahoo! Answers users about ways to improve health care.

Obama’s LinkedIn profile outlines his career as U.S. Senator, lecturer and Illinois state senator.

Rudy Giuliani is also on LinkedIn. Giuliani even has two endorsements, praising his work as mayor of New York City with his top qualities listed as “Great Results, Personable, High Integrity” and “Great Results, Expert, High Integrity.” Caroline Giuliani doesn’t seem to be on LinkedIn, potentially saving her father some embarrassment.

Both candidates have chosen to hide their connections, just in case the likes of Bernie Kerik resurface.
