A little 'history' lesson. Many long years ago, I believe it was in Ireland or England, men in coal mines would hear 'something' knocking on the wooden timbers used to support the walls and ceilings of the mines hours to days before a major cave-in. The survivors decided the 'knockers' were demons and they were knocking the timbers to pieces, causing them to collapse. They called them, 'Tommys'...but their actions were added to the name...thus, 'Tommyknockers'. We, America, are in a 'mine shaft' and the democrats are knocking on the timbers. So this poem 'fits' our situation, methinks.
