The trouble with opinion polls is, they make you believe all the electorate will vote for one or other party. They don't tell you the percentage of those who wouldn't vote any party.
Turnout at the voting polls in Britain is getting lower all the time.
As we can see locally, some parties do just absolutely NOTHING!
Other parties campaign all year through, notably on Dover Forum.
Here we have Keith and Reg, for Labour, verses Barry for Conservatives.
We have Philip of the climate change party

.
Then come PaulB's fulminations at the LibDems, followed by Brian's euroland party

, and a platea of members who have openly rebelled against politics in every form and semblance.
I wish we could have a jokes page for politics local and national!
