Poll: Brits don't vote because they're furious with politicians

The republicans will get back into office again, fear not. Then after that the democrats. ad infinitum. You’re mistaking the concept of vote-strike with “sitting on your ass and not voting”. That’s akin to a work-strike being ‘sitting on your ass and not working’.
The difference lies in the demands you make, and working together with the other political persuasions. Strike is active. Not registering nor voting is passive.
I agree, low voter turnout is a problem as it could lead to the things you speak of. If it’s to work, it has to be the entire electorate on strike. That may be a pipe dream, but it’s not an impossibility if we pull together.
We need to stop dividing ourselves by our politics. We need to stop thinking of the other side as different. We all want a better life. We all love our kids. We all want a good job. We’re all the same. I find the concept of ‘us and them’ really rather sickening as it weakens us all when we’re divided.
The best “new strategy” as i see it is to stem the corporate flow of money into politics. If you have a better idea of how to achieve this, please speak.
