I find this extremely objectionable.
Here's what a gratuitous Joshua Green (who otherwise is reliably enjoyable) has to say about Rick Santorum's high-school yearbook photo:
A quick office straw poll here at The Atlantic, conducted amidst uproarious laughter, confirms that this is, in fact, the single worst year book photo that most of us have ever seen. An outright disaster. I suppose it's Santorum's misfortune to have been in high school during this era. I'm pretty sure that 1976 wasn't too kind to anyone. But still. Wow--he looks like McLovin in polyester. I have yet to meet the political consultant talented enough to spin this one. My condolences to Santorum. Brave of him to have struggled through this and made something of this life.
