From a Washington Post story by Maria Luisa Paúl headlined “Yelling ‘Hey John’ at the Capitol Rotunda will turn many heads”:

A new powerhouse is emerging in the U.S. Senate — but this one has nothing to do with politics.

In January, exactly 10 percent of all U.S. senators — 10 out of 100 — will be named John or Jon. Sen.-elect John Fetterman (D-Pa.) will be the latest addition to the John/Jon phenomenon, which was noted on Wednesday by Grace Segers, who covers Congress and politics for the New Republic journal.
