What does "caucus" mean as a verb?
For example, in this article: http://www.foxnews.com/story/0,2933,448477,00.html
it talks about whether or not Lieberman will continue to caucus with the Democrats. What does that actually mean? Can the rest of the Democrats actually force him to vote with them if he chooses to “caucus” with them??
