Between ISIS and Ebola, Republican lawmakers are demanding swift action to do whatever it takes to save American lives. But as Jon Stewart pointed out on Thursday night's "Daily Show," that demand doesn't extend to other major killers of Americans.

In recent years, Republicans have been preventing implementation of Obamacare, blocking attempts at gun control and even fighting efforts to improve the American diet.

"All keep hearing is 'we must do whatever it takes to save American lives' -- unless it's stopping the things that are actually killing Americans," Stewart said.
