I would agree with this statement, were it not for the uni-party. With the uni-party, even state legislatures are out for themselves. We the people mean nothing to them, so long as they line their pockets and increase their "power". They will do anything necessary to accomplish those two things. The current safeguards in place do not account for that fact.
The state legislatures are noticeably more conservative than the Federal government is. (That’s a low bar, granted.)
Besides, isn’t it in their self-interest as state officials to restore more power to the states and to move the Federal officials out of the way (if only in pursuit of their jobs)?
