Pick some images that more accurately inform the text (a dog with a car; Mitt posing alongside corporate goons, etc.,) and use a font that can be read more easily against any background (there’s a reason memes use heavy-outline Impact,) and you’ll have yourself some pretty sharp parodies.

Good start.
