Are you having a stroke, or is this one of those ""they are responsible for everything bad"" type of thing, where "they" is whoever you happen to want to send to Poland?
Or do you really believe that every single person who sat this election out is a leftist? It's difficult to tell whether you're hateful or just very dumb.
