The faction of Al Qaida reponsible for the Madrid bombings has endorsed George W. Bush:
"The statement said it supported President Bush in his reelection campaign, and would prefer him to win in November rather than the Democratic candidate John Kerry, as it was not possible to find a leader 'more foolish than you (Bush), who deals with matters by force rather than with wisdom.'" "In comments addressed to Bush, the group said:" "'Kerry will kill our nation while it sleeps because he and the Democrats have the cunning to embellish blasphemy and present it to the Arab and Muslim nation as civilization.'" "'Because of this we desire you (Bush) to be elected.'"
Of course, it goes without saying that Al Qaida has no more of an idea about how to fight terrorism than we do. But that same logic should apply to the bombings in Spain. Al Qaida wanted Aznar gone, but that doesn't mean it wasn't the right thing to do.
In the Spanish case this argument is likely irrelevant anyway. Many voters were more swayed by the government's cover up of Al Qaida's responsibility than by the bombing itself.
The Spanish people opposed the War in Iraq long before the bombing. They planned to re-elect Aznar inspite of his support for invasion, not because of it. The bombing simply put the issue back front-and-centre. The Spanish could no longer elect a Prime Minister who -- they believed -- had the wrong strategy for fighting terrorism.
