Sen. Barack Obama and Sen. Hillary Rodham Clinton have made their first joint campaign appearance, in Unity, N.H. They seemed to say all the right things to work as a team, and their body language suggested they were working off the same playbook, too.

What are your thoughts about former rivals Clinton and Obama now working together? Send a comment.
