Former White House advisor Steve Bannon is injecting himself into a Senate race here in Wisconsin. Bannon has endorsed Repulican Kevin Nicholson, who is facing state Senator Leah Vukmir for the chance to try and unseat Democrat Tammy Baldwin in November of 2018. Nicholson is a political newcomer. Vukmir has been a state lawmaker for 15 years. The race for Baldwin’s Senate seat is expected to one of the most hotly contested races in the country. Also one of the most expensive.
