Consistently Conservative for over 30 years. Labour are always guaranteed to leave the country deeper in debt, and I've never understood what the Liberal Democrats are for - though since the EU referendum it has become clear that they are neither liberal nor democratic. And Labour are far too far to the left for me. All Jeremy Corbyn ever does is moan that not enough is being spent on anything, but he has no clue how to raise any more money to pay for it. The Labour 2017 general election manifesto provided no answers - it had a £250 billion black hole in it. If you're going to say that your manifesto is costed, at least cost EVERYTHING in it, not just the recurrent budget.
It's about time Labour proposed a significant rise in income tax to pay for all their promises, but of course they won't because being honest will lose them votes.
Meanwhile, my view of the Conservatives is that they are a pragmatic party who understand how to run an economy. If you're going to create jobs, it's only businesses that are going to do it, so going easy on business just makes sense. Labour hates businesses - at least John McDonnell does.
Proportional representation has of course been Lib Dem policy for many years, but that is guaranteed to ensure there is never a clear winner. It will produce the need for a coalition every time, and the British people can't get their heads around coalitions. Liberal Democrat voters certainly failed to in 2015. Personally I have no problem with coalitions and they work perfectly well in the rest of Europe, but naturally neither Labour nor the Conservatives will go for proportional representation as they do so well out of the current system.
