Senator Charles Grassley is the most Iowa man in Iowa. He’s 82 and has aged in the Iowa manner, by looking like a child who fell into a food dehydrator. His Twitter is a delight. He is a Republican in the Chamber of Commerce tradition, representing that wing of the party whose ambition for government is to get it out of the way of farmers and insurance agents. This approach has gotten him labeled a Republican In Name Only, which is the kind of accusation people who learned about politics from Glenn Beck will level at a man who has been in the US Senate for 34 years. But despite the certainty that he will spend the rest of his life in office—or maybe because of it—Grassley displays the most Iowa quality: he wants to do a good job. Yesterday, he announced he might hold hearings on President Obama’s Supreme Court nominee after all. His decision may have something to do with this jeremiad in the Des Moines Register.
