Can someone explain Super-Delegates to me please? nt

who get to vote for their preferred candidate at the convention.

for the candidate of their choice. Some super delegates have 'pledged' for candidates, but can change their mind up until the time their state votes at the National Convention.

Are they distributed/assigned to regions across the country?

Do they decide entirely on their own? Or do they talk to party folk in order to decide? If so, whom?

Well, it's the Governor and Lt. Governor and Party Chair and all the members of the U.S. Congress (as well as others) from each state. So they are distributed all over the U.S.

Their vote is their vote, they can take the advice from people from their state or go out on their own. They equal one vote at the National Convention and are not beholden to the delegate selection from their state convention.

Here's a web site that might help you:

Sort of. All Democrats in Congress and other party officials are super-delegates. The Republicans have a similar designation of "unpledged" delegates, but the Democratic party has more of them than the Republicans do.

The superdelegate were added after Nixon's near-record-breaking defeat of McGovern in 1972. McGovern was a popular candidate, but he was not polished and made some dreadful campaign mistakes. After that, the Democratic Party decided that having 20% of the delegates be uncommitted would allow the party cognoscenti to moderate the nomination and help ensure that someone electable was chosen. Superdelegates do not have to pledge their vote to a candidate beforehand, but many of them do. I believe that they can also change their votes later, if they wish. Currently, Hillary Clinton has a commanding lead in delegates if you include the superdelegates who have promised her their vote.

enrage your base.

The Republicans may wish they had more superdelegates this year.

I would be more comfortable with the "moderating" effects of the superdelegates if so many of them weren't in the DLC.

Anyway, there are full delegate counts here: http://www.cnn.com/ELECTION/2008/primaries/results/scorecard/#val=D
