At the risk of playing devil's advocate - surely any military organisation is communist?
Consider:
1) Central planning
2) Free dental and medical as required
2) Uniform provided to remove individual differences
4) Meritocracy (i.e. promotion on the basis of demonstrable skill)
5) Money is not the overriding concern - results are.
6) From each according to his ability (Trade/Rank) , to each according to his needs
I'll get flamed for this, but if you would prefer society to more reflect the military, then voting for the left would seem to be the way to make that happen.
Oh ,and you don't get to vote to change the leadership ;-)
