Its an interesting idea but who would compile and publish this info ?
A Government Dept. perhaps, like the ONS ?
Whoever provides these "Facts" will have to get them from somewhere. If we are to be expected to know 100% of what is possible to know, there wouldn't be any time left to vote !
In my experience, most voters stick to what they know and what they have always done. Also, what about the people that say :::::
" Well, I have my mind up, now please don't confuse me with the facts "
Politics is an art, not a science, whatever the pointy heads tell us !
