Looks to me like after the next general election, we'll either have a Labour or Conservative government
For those hoping for a Conservative government (!) consider this:
Labour's major funding comes from the trade unions, which means there is a very real possibility that with the threat of a withdrawal of funding, a Labour government might have to bow down to the pressures of the trade unions over the interests of business (as happened with the temporary workers). I think Labour is scared of businesses, and the economic impact that could result in not appeasing them (if what's bad for the economy leads to job losses etc then voters won't be pleased with Labour). However, I don't think there are many in the Labour government that actually support the interests of business over those of the trade unions. However, contrast that with the Conservatives, who have no trade union pressure and actually support the interests of businesses ideologically.
Labour might not be everyone's cup of tea, but there is no way you can claim to support the working classes if you actually want the Conservatives to win because if you think the working class are suffering now under Labour, you ain't seen nothing until you see how much they are suffering under the Conservatives...
