Obama's Favorite Rhetorical Fallacy?

Karl Rove notes Obama's love for straw men:

On Tuesday night, Mr. Obama told Congress and the nation, "I reject the view that . . . says government has no role in laying the foundation for our common prosperity." Who exactly has that view? ...

Mr. Obama also said that America's economic difficulties resulted when "regulations were gutted for the sake of a quick profit at the expense of a healthy market." Who gutted which regulations?

Even in an ostensibly nonpartisan speech marking Lincoln's 200th birthday, Mr. Obama used a straw-man argument, decrying "a philosophy that says every problem can be solved if only government would step out of the way; that if government were just dismantled, divvied up into tax breaks, and handed out to the wealthiest among us, it would somehow benefit us all. Such knee-jerk disdain for government -- this constant rejection of any common endeavor -- cannot rebuild our levees or our roads or our bridges."

Whose philosophy is this? ...
