It seems reasonable enough when I read it, due to his conversational tone. But now let me sum up:
"It's the Special Interests! They did it! And if we get rid of it we destroy their power!"
Doesn't seem quite so reasonable in that case, does it?
I do think it's an interesting point that as per Madison in the Federalist Papers the original Senatorial Election method was designed to create "gridlock." I just don't see how it would really be all that effective at it, as the State Legislatures are still elected by the General Populace. How could it be thought that the State Legislature would have a different agenda than the General Populace? And if they have basically the same agenda, why not remover the middleman and just have the General Populace elect the senators anyway?
I imagine that this is probably the same argument that took place back then and which led to the passage of the amendment. It makes a lot of sense to me, at least.
