The income tax amendment is out of the Senate. If the House concurs, it's to the voters.
Some of us remember when Rochelle & Naifeh came very close to enacting an income tax.
They contended that it did not violate the state constitution.
Enough ambiguity existed that almost half the legislature was prepared to enact it.
Not such a crazy idea to resolve the ambiguity. Judges, even Supreme Court judges, give "creative interpretations" from time to time.
They have, with a straight face, interpreted "elected by the people" to mean "appointed by the governor."
