How can it only be "possible" and then turn in the same breath say that the date "has to be" - typical tap dancing by these people.
On some of the pages I worked on, the date was just "11". And . . . you have to wonder at the million + signatures. I saw some pages with only five signatures and one that had a single entry. I half suspect, as a previous poster suggested, that the anti-Walker people figured 10 signatures to a page by x amount of pages turned in and voila! over a "million" signatures.
