Historically, the choice for campaign buttons has always been the 2.25-inch button; I like Ike, and Ike liked a 2.25-incher. But with this year’s crop of Chicago political button orders we’ve seen a variety of different sizes. Oval buttons, square buttons, even cute 1-inch round buttons— they are all hitting the campaign trail in 2011.

With local Chicago elections next Tuesday, we expect to see campaign buttons galore on our morning commute. And maybe Rahm Emanuel.
