One lesson seemingly beyond the scope of the current crop of Conservatives is that politicians are elected to serve the interests of the majority - full stop.
Marginalizing the country's potential with the sour substitution of fear will never lead to progress and incessant self promotion is a contradiction of critical thought. When mired in the intellectual muck, don't think for a moment the rest of us will want follow - get a good mirror and try introducing some humor into your self examination.
 
Then again, the Conservatives could save the country some grief and recuse themselves from the next election - good for us and comfy for them to just blow a bubble and pad their cocoon.
