If you eat sweet potatoes, there's a good chance that the delicious bounty came from the Nash County farm of Sen. Lisa Stone Barnes and her husband Johnny.   The two-term legislator (one term in both the House and Senate) sat down with Skye and Brian to talk about her love of agriculture, her extensive family, politics, and her work in her community inspired by her Christian faith.   Plus, we are inside a month before the primary election and the opening day of the short session.  Skye and Brian update listeners on the latest from the US Senate race, the race to replace Congressman David Price gets ugly, another presidential-run mention for Governor Cooper, and more.   The Do Politics Better podcast is sponsored by New Frame, the NC Travel Industry Association, and the NC Beer & Wine Wholesalers Association.
