This crazy idea has been rattling around in my skull for some time.

It involves a state income tax for Texas. The idea is this: If Texas legislators are so sure-fire certain that a state income tax never would be approved by rank-and-file Texans, why don’t they just put the issue to a vote and let them decide this issue once and for all?

My pal Enrique Rangel, writing for the Amarillo Globe-News, talked to some leading Texas pols recently to get their take on ways to improve the state’s rickety tax system. Tea party Republican comptroller candidate Debra Medina favors a consumption tax to pay for public education; state Sen. Bob Duncan, R-Lubbock, favors a statewide property tax to pay for schools; Fort Worth Democratic state Rep. Lon Burnam wants an income tax.

Of the three ideas, I kind of like the idea of an income tax coupled with property tax relief.

Here’s the problem with an income tax: It requires an amendment to the Texas Constitution, which requires a statewide popular vote.

The Legislature, in a silly act of buck-passing, decided some years ago to require a constitutional amendment election, believing it didn’t have the votes in the body to approve an income tax by itself. Legislators figured that such a monumental decision needed voters’ stamp of approval.

They knew all along Texans wouldn’t approve such a tax, even if it could be structured with a serious offset somewhere else, such as local property taxes.

The state has been dancing all over this issue for as long as anyone can remember. Only lame-duck politicians — and a few active pols living in districts where they won’t be threatened with electoral defeat — have had the guts to talk openly about reforming the state tax system with an income tax.

It’s an open secret that an income tax would enable the state to keep its public school system from courtroom fights when judges rule the financing system to violate the state’s Constitution.

So, why not put the issue on the ballot. Burnam’s idea goes nowhere every time he pitches it to his legislative colleagues.

If it’s such a bad idea that’ll never fly with voters, put it on the ballot and let’s decide it.
