Anthony Weiner
By now Anthony Weiner has had more sexting scandals than we can count. The New York congressman-turned-convicted sex offender is responsible for sending lewd photos to over a dozen women (at least) via the internet over the years, masking his illicit online activities under the pseudonym "Carlos Danger," sexting while watching his children, and finally, sexting a 15-year-old girl, for which he was sentenced to 21 months in federal prison.
Weiner's utter inability to keep it in his pants (and stay off Twitter) led to his deserved downfall. Thank god Huma Abedin finally ditched his ass by then.
