BarryW, Vic's formula is simple now I've thought some more about it:
1. Conservatives - only for rich old duffers who hate change. Imagine!!!
2. Labour - only for the poor working class. Rich lefties need not apply.
3. LibDems - for the middle earth folks who like a bit of trendy leftism, wrapped up in safe right wing policies.
4. UKIP - only for those with a myopic loony outlook on Europe.
5. Green - first time voters only
6. MRLP - Vic's next party
Unemployed have no value in this scheme, cannot be attributed to a particular party and don't vote of course.
