"brainwashed" is another misused word.

In the case of someone voting for a party that will grant them a survival without condition, there is no "aopting radically different beliefs", not necessarily anyway. I can see how some people might vote for a party for no reason other than getting their benefits, and where that party otherwise represent views that the voter opposes, than yes, maybe we can use the word "brainwashed" in its proper context. But how many people that rely on state handouts meet this criterion? I certainly wouldn't vote for a party that would bring in the death penalty, and a unconditional unemployment benefit. I could overlook minor political differences, but unless we find a political party that exactly matches our own ideology, then we all make these compromises when voting.

A party's policy on state handouts is but one aspect of their electability. Those who fail to realise this, well I'd hope they're in the minority, but truth be told, I have no idea how many people we're talking about here.
