Republican Party members in Wisconsin will hear from leaders like Governor Scott Walker, Senator Ron Johnson and outgoing House Speaker Paul Ryan this weekend.  The party’s annual convention runs through Sunday in Milwaukee.  Choosing a candidate to run against incumbent U-S Senator Tammy Baldwin will be a crucial decision among the weekend’s activities.  The endorsement is important for both state Senator Leah Vukmir and Kevin Nicholson.  This year’s convention has the theme of “Delivering Results, Moving Wisconsin Forward.”
