The title says it all.
Reason 1: Conservative Councils charge lower council tax than Labour or Lib Dem councils.
ConHome writes:
Analysis of the Council Tax figures has shown that Conservative Councils charge an average Council Tax of £1,144. For Labour it is £1,161 and the Lib Dems £1,231. This is based on Band D Council Tax.
This is also illustrated by this graphic:
This has been achieved despite:
a) Labour fiddling the funding formula in order to subsidise the less efficient Labour councils.
b) Many new Conservative councils having to raise council tax in order to pay off debts incurred by previous administrations.
Reason 2: Conservative MPs charge less on expenses
Guido has the averages worked out:

While this is in theory still far too much money, I see politics as being inherently imperfect. And as I am always prepared to tell people on the doorstep, the Conservative Party is the least imperfect option of them all.
In my mind these figures also neatly illustrate why voting for LibDems as a protest is always a bad idea. Not only do you get worse representation than with both Labour and Tories, you get more expensive representation as well.
