How do political parties choose there leaders?
This last part may have been true in the earlier history of U.S. politics but is not true today. The political parties have lost significant power in the poltical system as it stands today. A prime example is Sen. McCai, the Republican nominee for President. The base of the Republican party did not want him to be the nominee, several influencial members of the party threatened to boycott the 2008 election if he was chosen as the nominee. The smoke filled rooms are a thing of the past when it comes to important U.S. offices.
