You mean, people are not allowed to talk publicly about politics? Sure, that's a great idea, that would bring about the renaissance of democracy. Or you mean they only can talk about politics where not too many people can hear them, like on their kitchen - a-la Brezhnev times in Soviet Union - is OK, but on TV - no-no, it's "political advertisement". And helping to elect a person with ideas which you share is not allowed too - it's "donations". Well, not that you'd know their ideas anyway, because political advertisement is banned, so unless you come and talk to them personally you won't know that.
