Low key, young looking David Plouffe has been Barack Obama’s campaign manager since the beginning of 2007. He refuses interviews and attempts to keep his name and his family’s names out of the press. Barack Obama has heaped praise upon him. Plouffe is credited with the strategy of contesting all the minor state caucuses, which gave him the slight, but unbeatable edge in delegate count that Hillary never overcame. The caucus states are decided by a very small number of active party members. It wasn’t too difficult to recruit enough new voters to swamp the caucuses with Obama supporters. In most cases Obama was able to win all or nearly all the delegates, unlike the hotly contested primary states where Democratic Party rules split the delegates between the two contenders.
