Johnny Isakson, Georgia’s junior U.S. senator, by many accounts, is a sane, pragmatic moderate when compared to many of his GOP brethren (and the post-2000 version of Democrat Zell Miller, for that matter). That’s why his support of the Linder/Boortz Fair Tax boggles my mind somewhat.

The Fair Tax, you might have heard, is a proposal to do away with the federal income tax and fund government with a sales tax. Here’s the bizarre twist: it would give lower income families refund checks for taxes they paid on vital goods.

Why not just, umm, not tax people to begin with? Does this proposal not create the same sort of bureaucracy many Fair Tax advocates claim to despise? For that matter, don’t those checks sound an awful lot like the same sort of welfare many of its proponents claim to despise? Doesn’t it create more reliance on government, not less?

It’s a utopian fantasy that would be a disaster in practice. I can’t fathom how someone like Isakson would throw his weight behind it. Then again, Isakson’s voting record isn’t all that moderate. His “moderate” label can only be justified cosmetically, not substantively.
