Why Bush Needs Lieberman
By Sidney Blumenthal
For the Democratic Party the Lieberman problem is a serious one. After his primary loss he has become the de facto Republican candidate, virtually endorsed by Bush, Cheney and RNC chairman Ken Mehlman, who have withdrawn support from the actual Republican candidate in the race. Lieberman can only win by securing almost all the Republican votes. His campaign must pull Republican votes to the polls, courtesy of the national GOP on which his ambition has become dependent. That can have a drastically negative effect on the Democratic campaigns in the three Connecticut congressional districts where Republican representatives are at risk. Those three seats comprise 1/5 of the total number of 15 that Democrats need to gain the House. Out of necessity
Lieberman has become an active obstacle to Democratic victory and one of the key bulwarks for protecting Bush's one-party rule essential for remaining unaccountable for the rest of his presidency. For Bush, that is the importance of Lieberman.
