John Fetterman stunned the GOP crowd with a surprise video appearance at Republicans’ Trump-a-Palooza midterm convention in Dallas. The Pennsylvania Democrat introduced Republican Senator Dave McCormick, declaring himself a “common-sense Democrat” who stands with America. Fetterman also vowed to reject “extremes and socialism” and said he would work with Donald Trump to defend Pennsylvania’s steel industry. The extraordinary cameo came as Republicans packed the two-day convention with attacks on Democrats and praise for Trump. Fetterman’s appearance highlighted his growing break with his party’s progressive wing and prompted fresh questions about his political future.
