Where's there's a hot topic issue, the Republicans will come out in lockstep with voices on the same wavelength. They use clear and simple language with a single antagonist. In the really big battles they even coin phrases like 'Obamacare', 'Death tax', & 'energy exploration', that succinctly convey their point of view. Each of those phrases will be used repeatedly by every Republican on TV, until their opponents (Democrats) even adopt the same language they've invented.
This why I like that 'shoplifter in the store' analogy. Its pretty simple and relatable to just about anyone. On the topic of language though, the opponents of SOPA should be creating their own word/phrase. If we refer to SOPA as 'online piracy', then we've already conceded more ground that we need to.
