why can’t nebraska threaten to secede from the union if obamacare is passed?
Because the representatives are wusses and afraid of being called names.
IIRC Richard Shelby was threatened like this early in the first Clinton Administration.
He switched parties. Nelson has the option to do exactly the same. It would be nice if, in doing so, he just happened to release phone tapes of Rahm or whoever threatening Offutt.
