Amazing that you need this explaining to you.
You see how the gap has widened overall ? On the left is represented the new Corbyn party etc. most centrists arent there.
On the far right is reform, where by your own reckoning most people have moved to . The middle area of new labour, libdem and Tory is still there, in around the same place, with the same amount of support (some of it floats some doesn't).
You are not the guy in the middle as you claim. You are reform, by your own admissions. You've been hoodwinked again
And you do realise this cartoon was about USA politics? I didn't ever have you down as an Obama supporter, EVER. Which is where you claim to be if you were the guy in the middle
But it does show how easily you are led, because the diagram looked funny.
