Only pr can stop socialism

First past the post is good for socialism because when the choice (for voters) is reduced to just two political parties it is unlikely that people will choose the party of the right. We can assume that most voters want some form of socialism (otherwise democracy is redundant) so they will be reluctant to risk losing it by voting for the party of the right. Given that fptp favours the left it is strange that the party of the right do not realise this and support pr. It is strange to think that the party of the right do not realise that expecting non-socialist voters to have the disciple and loyalty to vote for them is fanciful. The party of the right assume voters will have the loyalty and discipline to vote for them in a fptp election... even though this discipline is not required in a pr system. Non-socialists must be loyal to a party which has the ability to make that loyalty unnecessary. The right must vote for (for example) the Tories only because the Tories reject pr... so in that sense the Tories are using blackmail against the right-wing voter. With socialism (provided by the party of the left) acting as the threat. The Tories get into power by making Labour look terrible and using fear to get people to vote for them. With fptp they are the only alternative to socialism. It is only if the Tories prefer being in power to a greater degree than they dislike the country being ruled by Labour that it makes sense for them (the Tories) to support fptp. In order to (avoid pr and) remain in power they are prepared to risk the country being ruled by Labour. Tories fear (hate) pr more than they fear being ruled by the Labour party.
