Coincidence? You be the judge. What's clear is that, as is typical of Bush's operations, the program was run without regard to the law. The Christian Science Monitor:

The $42 million cutting-edge [ADVISE] system, designed to process trillions of pieces of data, has been halted and could be canceled pending data-privacy reviews, according to a newly released report to Congress by the DHS's own internal watchdog.

Data mining to help fight the war on terror has become an accepted, even mandated, method to provide timely security information. The DHS operates at least a dozen such programs; intelligence agencies and the Department of Defense employ many others.

But ADVISE (Analy­sis, Dissemina­tion, Visu­ali­zation, Insight and Semantic Enhance­ment) was special. An electronic omnivore conceived in 2003, it was designed to ingest information from scores of databases, blogs, e-mail traffic, intelligence reports, and other sources, government documents and researchers say.

How reassuring. (And it would certainly work for domestic politics, too, eh?)

So, what could go wrong?
