I was responding to Hockey who stated that an income tax may force him to move out of the state.
The advantage of having a tax is that it continually draws attention to government spending.  While money was pouring in and no one had to contribute, legislators spent on all sorts of stupid stuff and gave our oil income away (SB 21...) and no one paid attention.  Kelly's plan would again allow the legislature to operate under the cover of darkness.  Do you really think he won't be back for more in a couple years when his magical new revenue doesn't materialize and he's burned through our savings?
