[Denting Left Wings Winning Streak]

David Crowley, a centrist candidate, has won the primary election to become the Democratic candidate for Wisconsin governor, according to a projection by CBS News' partner, BBC. The victory marks a surprise result that dents a winning streak for the party's left wing.

Crowley, who serves as the chief executive officer of Milwaukee County, secured a narrow victory over Francesca Hong in the contest. His campaign focused on issues such as making life more affordable, strengthening schools, creating good-paying jobs, and ensuring opportunity reaches every corner of the state.

The outcome is a significant departure from recent trends, where anti-establishment Democrats have notched up victories that have rattled party leadership in Washington. However, this trend continued in another closely-watched Democratic contest in Minnesota, where candidate Peggy Flanagan secured the nomination for the US Senate race.

Crowley's victory has implications for the control of the US Congress during the upcoming midterm elections. The state's political matchups are expected to be closely fought, with Crowley facing Republican nominee Tom Tiffany in November's governor's race.

Tiffany, a US congressman and Trump supporter, has highlighted affordability issues on his platform, including lowering taxes, supporting farmers, and improving healthcare. Crowley's campaign emphasized the need for a more pragmatic approach to governance, which may appeal to voters disillusioned with the party's left wing.

Crowley expressed his enthusiasm for the win, stating it was time "to get to work" on implementing his campaign promises. The victory marks an important turning point for the Democratic Party as it navigates its internal divisions and prepares for the November elections.
