Blogging political scientists are useful killjoys, constantly reminding us that the things that feel like they matter most in daily political warfare usually matter not at all, or very little. Reagan's ability to sway public opinion from the bully pulpit? A mirage. The 'driver's license' debate debacle that killed Hilliary's momentum? It didn't. The Etch-A-Sketch candidate, etched in stone? It'll shake clean by fall.
But this time I don't buy it. That is, I don't buy Brendan Nyhan's debunk in Columbia Journalism Review. Nyhan has two beefs about the coverage of Eric Fehrnstrom's Etch-A-Sketch gaffe: an ethical complaint about the way Fehrnstrom's remark has been interpreted, and a debunking of the widely forecast likely dramatic effects. On the latter front, I suspect he may be partly wrong. On the charge of unfairness to Fehrnstrom and Romney, I think he's almost completely off base.
