2018 United States Senate election in Wisconsin

From Wikipedia, the free encyclopedia

The 2018 United States Senate election in Wisconsin took place on November 6, 2018, to elect a member of the U.S. Senate from Wisconsin. This election coincided with a gubernatorial election, U.S. House elections and various other state and local elections. Incumbent Democratic senator Tammy Baldwin won re-election to a second term, defeating Republican nominee Leah Vukmir by more than 10 percentage points. This was one of ten Democratic-held Senate seats up for election in a state Donald Trump won in the 2016 presidential election. The primary elections were held on August 14, with a filing deadline on June 1. Baldwin was unopposed for the Democratic nomination, while Vukmir defeated Charles Barman, Griffin Jones, George Lucia and Kevin Nicholson in the Republican primary.[1]

Results

Despite initial expectations of a potentially close race, Baldwin ended up winning by over 10 percentage points, which was the highest margin of victory for a Wisconsin Democratic statewide candidate in 2018. She ran up the margins in the traditional Democratic strongholds of Milwaukee and Madison, but also won in western Wisconsin, Green Bay and most of the counties bordering Illinois, including Racine, Rock, and Kenosha counties.[143] This was the largest margin of victory for the Democrats in a major Wisconsin statewide campaign (presidential, senate, gubernatorial) since 2008.
