Visit to Military Base?

Hey, blogosphere/twitterverse: What kinds of things would happen if a liberal, anti-war Presidential candidate were to visit a Marine base on a campaign stop? I need some help here because I don't know the following:

• Would there be a protest? Where would it be? Outside the base? the building?
• How big would the crowd be? Would anyone show up? What would their mood be? What kinds of questions would they have?
• What would the be absolute WRONG thing to say to a room full of military families and personnel on a base that has sent troops to the Middle East?

Leave me a comment and help a novelist get it right...or at least less wrong.
