This means we’ll need to take the time to review the numerous candidates asking for our vote. In the days and weeks ahead, we’ll hear their messages, pre-planned sound-bites and Idebate statements. But, will we really get to know them? The four candidates we are about to profile here –Tiffany Shedd, Sine Kerr, Tim Dunn and David Cook – have a unique but common story: they are all currently in and from agriculture. Many of you know them; they know us, or at least the Farm Bureau family because every one of them is a Farm Bureau member. We also asked these four “aggie” candidates the same question: What does your experience in agriculture bring to your candidate profile?
