Seriously, I wish there was a comparison ratio between occupation and infidelity rates.  My guess is that politicians would rank right up there with professional athletes (if not surpass them). 

Just disgraceful news out today, reported by Politico:

Rep. Mark Souder (R-Ind.), a former congressional staffer who was elected to the House in the Republican revolution of 1994, has told colleagues he will resign Tuesday because of an affair with a female aide, a House GOP official told POLITICO.

Souder has scheduled an announcement about his future for 10 a.m. today at his congressional office in Ft. Wayne.

Souder is married and has three children.

He informed Minority Leader John Boehner (R-Ohio) of his decision on Sunday, according to GOP sources.
