4000 ? 100,000 ? & $4,629

During the next six weeks before the Pennsylvania Primary on 22April, a most sad but important benchmark number is likely to become reality.

It is the number 4000.

If you don't know what that number represents, then the number itself is even more important. The numbers 100,000 and also $4,629 should be making news and re-inserting themselves into the public conscience as well.

And what impact will the number 4000 have on the national discourse on the issues of the day when it arrives?
