As long as you have been here, I am saddened that you would even ask that!! There are no words!
This obviously isn't 0bama/Biden, and I don't see it as W/Cheney. Clinton/Gore? No, Algore was completely useless even then. Nixon/Agnew? Ryan doesn't fit the role. Roosevelt/Truman?
What influence Ryan does have regarding policy is not an idle question, it will be absolutely determinative for a large number of conservative voters, myself for one. We can discuss it somewhere else - this thread is a little raw for this sort of thing, but it's what we used to do on FR all the time. Isn't it? :-)
