Just something to ponder. For a couple years now, there’s been a growing chorus of pundits, analysts and — most significantly — conservative reformers who’ve claimed to one degree or another that the GOPs anti-tax posture has lost its political salience. There are good arguments on that score, and bad ones. But it seems to me that the tax issue is on its way back. And while nothing is certain, I think it’s reasonable to argue that the obituaries for tax cuts as a winning issue for Republicans were almost surely premature.
