“Even a bribery conviction would not automatically force Mr. Menendez from office, under the Senate rules. He would either have to voluntarily resign his seat, or two-thirds of his Senate colleagues meaning 15 Democrats would have to vote to expel him.”

Felony is perhaps the highest qualification to be a politician in the country.
