I'm not sure, supercat. Wouldn't the legislators neglect to attempt that at the earliest opportunity amount to tacit consent, therefore not forced to accept the Amendment?
I'm sure some would argue that. On the other hand, states would have had no basis for complaint until such time as there was a disagreement between their desired policy and the one desired by the feds. If the state legislature doesn't object to the Seventeenth Amendment prior to a particular Senator is seated following election, they could be reasonably regarded as having agreed to that particular Senator's appointment. That does not imply that they agreed to appoint all future Senators by plebiscite, however.
