In Korea, in theory at least, it's different. The law says they can only campaign officially for a few weeks. They certainly do it with gusto. Here we have a typical scene. The sign-carriers are supported by a crew who dance to the candidate's theme song blaring from the sound truck.

Of course, like politicians everywhere, Koreans are experts at using the news media to get their messages across. So in the end, the law limiting their campaigns doesn't really make much difference after all.
