Should those that do not live in the country be allowed to influence decisions which they will not have to live with? Are Poles abroad knowledgeable enough about Polish politics and reality to vote in national elections? Should this be allowed or at least taken only most seriously.
Of course they shouldn't be allowed to vote. Anything more than 5 years out of the country should immediately disqualify you from voting in elections and referenda - unless on official Polish business, such as being an ambassador.
You just need to look at the last few elections to see how Polish Americans have voted - often after being in possession of some very wrong 'facts' about the candidates. I read so much rubbish about Kaczynski being the "conservative" candidate last time, for instance.
