Toomey, the retiring Republican senator, said that, based on what he’s seen of Fetterman’s recent public appearances, the Democrat’s communication struggles mean he could not be an effective senator.

“As someone who served in the United States Senate for almost 12 years now, I have a really good understanding of how the place works,” Toomey said. “If John Fetterman were elected to the Senate, and he’s not able to communicate, if he’s not able to engage with the press, if he’s not able to engage with his colleagues, he would not be able to do the job. It’s just not possible.” …

Toomey pointed to a recent MSNBC interview in which Fetterman said that he was “feeling fantastic” and that the only lingering effect was missing a word or two or mushing two together.

“If that’s all true, then why won’t you agree to debate Dr. Oz?” Toomey asked. “He’s either not as well as he claims to be, or he’s afraid to be called out for the radical policies he supports.”
