People are not loyal to the Tories

Part of the problem with the Tory (anti-socialist) position where fptp is advocated is that voters are not generally sufficiently loyal to stop Labour. The fptp system requires that voters even Labour supporters need to be loyal to their chosen party. They cannot drift away and vote for their naive non-tactical choice they must work out which party has a chance to win and vote accordingly. This means that for socialism to be prevented voters need to be loyal to the Tory party. But the problem with this is that people do not like voting for a party such as the Tory party in order to prevent a victory for Labour. People do not like being loyal to the Tories which means fptp is very helpful to Labour. Labour would do much worse under pr which means that Tory support for fptp is part of the reason Labour thrive. The Tories are keeping Labour in power as a consequence of their support for fptp. People are not loyal and so the fptp voting system is flawed.
