I've studied U.S. Senators.
I suggest we all do.
Those 100 bipeds are different from us.
A few appear reasonable, Rand Paul for example.
Most if not all are aliens of some kind.
It appears that the Dem has been chosen to win the PA race. Kathy Barnette is not alien enough for that group.
I'm absolutely certain if Barnette gets the nomination, the Dem wins.
Which is probably fine.
Because Oz would vote the wrong way in the important votes anyway.
BDT.
