The fact is that they WON'T be the same slobs. Beyond being beholden to the state legislature, MANY states would flip flop sides.
We would lose 8 seats in LA, MS, AL, CO, and ME but pick up 8 seats in ND, SD, MI, IN, WI.
There will be other flip-flops as well, but those are some of the key ones.
RINOs would tend to die out in the Senate as well because most of them come from states with democratic legislatures.
I seriously doubt the situation would improve here in MA. If the state legislature had the power to appoint Senators the position would become one of political payoff much like the members of the Turnpike Commission. Granted, I don't see us doing much worse than Kerridy (the only difference between the two is that one had to marry his money.) At least there is some direct accountability to the people. I happen to like Gordon Pym's proposal that people who receive government largess not be able to vote. That would stop government from being a channel from my pocket to theirs.
