"Let no crisis go to waste," was a comment by Tony Rezko in 2008 regarding how Obama would handle a crisis.
This is a political thing in general, not an Obama thing. Both parties do it. Bush did it, but really everyone was complicit in ramming the PATRIOT Act through so fast, you would have thought it was a bill to resurrect Jesus Christ himself. The very best examples come from presidential candidates. Every time something happens, somehow the incumbent will share blame in it no matter what. It's strategy.
Sometimes, things are just political, not partisan.
He needs to focus on things that actually matter like terrorism and voter fraud. Poverty is still killing more people than bullets.
