I see you like to stick with the party line, and go the Clinton route.
The first definition does just fine, but, since I don't really care about the word, but more what I was pointing to by using it, I'll delineate for you a number of things I would need to see in order to properly qualify your analysis as cogent:
1. convincing or believable by virtue of forcible, clear, or incisive presentation; telling.
2. to the point; relevant; pertinent.
1. You demonstrate an understanding of our federal spending, revenues, deficit, debt, and projections for these going forward.
2. You demonstrate an understanding of what would happen if these items remained on their current trajectory.
3. You demonstrate an understanding of why Ryan has included each element of his plan that he has.
4. You demonstrate an understanding of what would happen to the items in (1) under Ryan's plan.
5. You demonstrate an understanding of why we must go from (2) to something akin to (4).
And, if you accomplish these tasks, but you do not think Ryan's Plan is the way to get to (4), then offer a counterproposal.
