It's a false choice you put forward. In critiquing her opinion you have exposed an equally abhorrent (to me and others) opinion -- in the words of Clinton and others who demagogue a point "The American people always get it right in the end."
Direct elections of Senators got rid of one set of problems in exchange for another set of problems. While we can disagree or agree over which set of problems is more desirable, direct democracy is still an ugly red headed step child
I didn't intend the post to be an apology for direct election. Peach's view is, imo, correct in that essentially the original scheme was states themselves had representation in the national legislature. Without the 17th, would we have the same federal involvement in K-12 education ... or even interstate highways? Would LBJ have had the senate votes for Medicare?
I think Reagan was correct when he opined that once people get a program or benefit of sorts .... govt cannot kill the beast of its own creation.
But, direct election was simply an invitation to graft. I don't see how the Founders could have envisioned a post-Civil War federal govt and the problems of graft. We have the 17th, and it's not going anywhere. Practically speaking, there isn't much chance of amending the constitution, which is one irony of Justice Roberts and Citizens United, but that's another issue.
It might be possible to put term limits on senators, and that arguably would make them less interested in reelection than governing.
