Conventional political wisdom dictates that Republicans have no shot at securing the support of the vast majority of labor unions. But a few cracks are starting to appear in the union love affair with the Democratic Party and offer the GOP a unique opportunity.

This week, Axios reported that the political action committee associated with the International Brotherhood of Teamsters, one of the nation’s largest labor unions, had donated $5,000 to Sen. Josh Hawley (R-MO). The donation came just a few months after the union made a stunning donation of $45,000 to the Republican National Committee in January, the union’s first such donation in 20 years.
