If you really need a better explanation of how Tom DeLay did all these unethical political activities, you must check out the Tom DeLay's House of Scandal. http://www.dccc.org/houseofscandal/main.html Of particular interest on the main page is the diagram that has Tom DeLay in the center. It is very well done.
Connected to the Tom DeLay page are other pages including one on Bob Ney http://www.dccc.org/houseofscandal/scandal-ney.html and http://www.dccc.org/houseofscandal/members/DeborahPryceOH-15.html Deborah Pryce.
