Virginia is a perfect example of the consequences of the 17th amendment. If the house of delegates were to select 2 senators, BOTH would be staunch conservatives.
Party interests would compete once again with States’ interests.
Even Senators from CA, IL, NY would have to look over their shoulders at their State Assemblymen who would not view kindly at the dozens of unfunded mandates forced on the States since FDR.
Senators liberated from the whims of the people could flip Presidents like 'Bam the middle finger and not suffer loss of office.
