Polite election campaign?

In the end of this month the gouvenor election will take place in our prefecture. That shouldn't really effect us in anyway, being gaijins, but yet the election campaign is taking up a big part in our life at the moment.
Our appartment is located on the main street in the city, and the walls are apparently thin, as we all day long can hear the 'onegaishimasu' yelled in the speakers on the passing cars, politly asking the people to vote for their candidate. One sunday morning we woke up 7 o'clock because of this!


The picture shows the election campain. The politician in suit is speaking to a fairly small crowd, while his yellow dressed crew is standing next to the truck greeting and bowing to every single car or bicycle that pass by.
