What's up with the "voter's" signs at Pimmit Today?

A primary is an early election to help determine who will be on the ballot for a later big election.  Today is a primary.   Although the USA has a number of political parties, most elected candidates are either Democrat or Republican.  In Virginia, you don't have to belong to a political party to vote in the party's primary.  Some Virginia Voters vote in the primary for the least-objectionable candidate in the opposition's party.

Is voting allowed in your country?  Is voting required in your country?  Do you think elections are usually honest?
