"'We have a spending problem, not a revenue problem,' [newly elected Senate Republican leader Dave] Cogdill said at a Capitol news conference.Because I'm pretty sure you'll find that line here. (Ctrl+F "spending" 3 times and you'll find it.)
Seriously, though, messaging, rhetorical device, narrative structure, none of these can be plagiarized. Riffed on? Sure. Used to death. Totally. But Obama didn't really plagiarize. Hillary hasn't. Few have. It is isn't lines of a thesis or book lifted directly from someone else's without a footnote, then it isn't plagiarism.
P.S. to the plagiarism accusation throwers: 1988 called and wants its scandal back.
