And Montana will not withhold those taxes either since it receives many other revenues from the fedgov than just highway funds. In fact, it receives $1.50-1.99 back for each dollar of taxes so pursuing this course will cost it big time. This is just grandstanding.
Not necessarily. If you're not getting any revenue from the feds, why not just keep what you collect? If you're collecting a dollar and then only getting, say, .50 cents back because you've lost your highway funds, why not just keep the dollar?
