Basically, you’re OK with a Senator simply being a statewide version of a Congresscritter.
Yes and no. Would I like there to be some high-minded ideal of Senators explicitly representing state interests ? Yes. But repeal of the 17th won’t bring us Henry Clays or John C. Calhouns again. You have a better shot with getting such a person elected by the popular vote than you ever would by the legislators (Ted Cruz a premier example of that, as had the legislature of TX elected a Senator, there’d be the RINO David Dewhurst in his stead). They’d only be interested in one thing, not protecting the states interests vis a vis the Constitution, but protecting and increasing their share of pork.
