hellokitty, I think you were thinking along the right lines with your post at 14:30, yes.
Traditionally, on the economy, "Left wing" politics feature higher tax, and greater public spending, and "Right wing" politics feature lower tax and lower public spending. That is a very big over simplification, of course!
Tax can be progressive, or not: progressive tax means that the more money you have, the higher tax you pay, like income tax. Non-progressive tax is where the amount you pay is the same, regardless of income, like VAT. Labour are more likely to be in favour of progressive taxation, as some believe that this is fairer and helps close the gap between rich and poor. The Conservatives worry about putting too much burden on wealthier people, as some believe this will reduce the incentive to work hard.
Within each party, there will be a range of views; Conservative party members might range from hardline right wingers, with very traditional values, through to more centralist politicians.
Likewise, within the Labour party, there is a range of political opinions, from hardline left wingers through to more centralist politicians.
For this reason, some people (like myself) change the way they vote from one election to the next, as the parties change direction.
Also, please remember that whoever you vote for, you are not obliged to reveal which way you voted to anyone, unless you want to. And your local MP is supposed to represent YOU, even if you voted for someone else.
