Governor Mark Dayton of Minnesota is a prominent left-hander. Here he is signing into law the state's same-sex marriage act:
Governor Dayton is a member of the Minnesota Democratic–Farmer–Labor Party, a party of the left.
How many U.S. governors are left handed? Let me know if your governor is a southpaw. I'll try to research this for a future post.
