Agreed, though usually, I see something besides that. For example, in other countries, they're sometimes actually saying something about their respective policies and current problems, how they intend to do something with it (and how the opponent will fail miserably at it).
In Poland, they engage in downright rude
ad hominem attacks and
almost nothing else. I know that all presidential campaigns have their share of insults, but a campaign composed in 95% of that? Come on. About 10 years ago, they at least used to insult the opponent's program and policies, now they don't do even that, focusing on opponent's past, personal life and other petty things. Also, 10 years ago, they didn't use language usually heard near vodka shops.
What's worst, this approach seems to actually work. The current prime minister won pretty much by the virtue of being comparatively nice and having a complete prick as an opponent. The president is even worse. Sure, he's nice and friendly, but neither bright nor eloquent. His opponent was... well, the same prick who was running for prime minister earlier.

Insane. Top that.
