These are SUPER delegates their votes count more than normal delegates and are usually party officials, such as congressman, former presidents and nominees, senators, and a few party heads, governors too I think, each party is different.
Amazingly, the Republican Party is more democratic than the Democratic Party in the nomination process. I believe that it was put into place so that outsiders and other unelectable candidates would get trumped by the insiders in the know.
Who will win: Dean
VP: Indiana Senator Bayh--rising star in the Democratic Party who is from the Midwest to stem Dem losses there (2000 Ohio, 2004 Iowa, Minnesota, Wisconsin)
