Today, the parties dig in as a bloc to obstruct each other. I don't think 60 state-appointed and obligated Senators would behave the same way.
State interests would be more important than party interests in an appointed Senate. Party interests become more important than state interests when parties fund the campaigns of Senators.

That could be true. But if you chew out people who gets elected now as a RINO or a wimp you may not like who your state legislators send to Washington. "State interests" may turn out to be the interests of state legislators and the people who contribute to their campaigns.
