Well stated. Today, very few catch on to the genius of having state legislatures select US Senators. The framers used human nature (greed and a desire for power) as a source to provide a check on the growth of federal government. The concept was that greedy state legislatures would not select Senators that would allow the federal government to grow and take over areas that would otherwise be handled by the state legislatures (thus keeping the tax base and financial power in-state).
Yep.
We have laws that allow the corporations to make “campaign contributions” not only to the campaign warchests of individual Senators who write the laws that affect us all, but to the NRSC which was founded in 1916 as the Republican Senatorial Campaign Committee. In practice, this functions as an additional guarantee that a Senator once elected, if he plays his cards right, is nearly impossible to unseat either in primary or general elections.
