If anyone put that leaflet in their windows, it was not enough for it to enter the national debate.
The much less contentious bus statement was debated, nationally and endlessly. The challenges to that statement would also have encompassed the leaflet claim if anyone had read it.
Why is this leaflet worthy of debate now?

Stu, any evidence that a significant number of people have changed their minds significantly more in one direction than the other?

What information has become available since the debate to make anyone change their mind anyway?
